Highlights

12 FUNCTIONS w/ OPTIONAL CADENCE SENSOR: BC 12.0 WL displays trip distance, speed, total distance, trip time, clock, total trip time, average speed, average speed comparison, maximum speed, and current temperature. It also provides monthly statistics and can be used with two different bikes. 12.0 WL ATS can be paired with optional cadence sensor available as separate accessory for the basic ATS computer, included in ATS CAD. Languages: English, German, French, Italian, Spanish, Dutch, or Polish.

WIRELESS DATA TRANSFER & LARGE BACKLIT DISPLAY: The wireless (WL) encoded transmission SIGMA has developed eliminates the need for cables. A wireless transmitter on the fork continuously measures and transmits bicycle speed without interference to the BC 12.0 WL's receiver. The 31 x 41 mm display has room for large numbers that are very easy to read during a ride. Especially practical is the BC 12.0 WL backlight, so the values can be read easily even when it is dark.

WEATHERPROOF, WITH LONG BATTERY LIFE: The BC 12.0 WL is water-resistant and weatherproof. The integrated, replaceable button battery (CR 2032) is sufficient to supply the BC 12.0 WL with energy for well over two years. During battery replacement, all total values and settings remain protected. The pre-defined tire sizes, ranging from a small child's bike to a 29" bike, make it easy to set the BC 12.0 WL. You can also enter the tire circumference exactly to the millimeter.

QUICK MOUNTING & EASY OPERATION: The BC 12.0 WL's handlebar bracket and speed sensor can be mounted quickly on the bike with cable ties (included). The bike computer is convenient to remove and store at any time. The wireless bike speedometer can be operated easily and intuitively with its three buttons. The two lower buttons allow convenient toggling among individual functions. The menu button takes the user to the settings and monthly statistics. 

VARIABLE MOUNTING OPTIONS: The BC 12.0 can also be used with the SIGMA OVERCLAMP BUTLER or LONG BUTLER handlebar bracket, available separately as accessories for handlebars with diameters of 25.4 or 31.8 mm. The OVERCLAMP BUTLER provides more space and order on the handlebars and a great view of the bike computer. The LONG BUTLER positions the bike computer away from the handlebars and encourages an athletic posture. There is option to fix with an additional screw to prevent theft.

Sporty statistician

Whether cyclists are commuting to the office, enjoying a long weekend tour, or speeding along with a road bike, the BC 12.0 WL is the ideal companion for all cycling adventures. This SIGMA ORIGINAL likes things sporty and versatile: the BC 12.0 WL provides cyclists with access to twelve functions, giving them an overview of their performance on two different bikes at all times. The wireless bike computer also provides monthly performance statistics. It is a true SIGMA ORIGINAL with lots of sophisticated functions!

Current speed is displayed continuously, and any value can be chosen as the second value. Slim design and angular shape look good, especially on a sporty bike. 

Those travelling outdoors want to know what the weather will be like. The BC 12.0 WL has an integrated thermometer displaying the current temperature. The wireless bike computer shows cyclists their personal statistics for the past twelve months. Total distance and trip time can be viewed. This “training diary” allows comparison of monthly activity.

The BC 12.0 WL can easily be mounted on a second bike, whether that bike be a road bike, city bike, or racing bike. After it is set up once, the BC 12.0 automatically detects which bike is being used. All that is needed to mount the bike computer on a second bike is a second bracket and transmitter.

What's included: Bike computer (including battery), bracket for wireless model, STS transmitter (including battery), magnet, mounting material, operating instructions

Does the job, but assembling by yourself is a nightmare
Size: 4 Panel-88'', Color: Black
Does it do the job? Yes, although as others said there are small gaps but it's not a huge deal. The price is also good. But the reason I'm giving it a 3/5 is simply because the assembly for this was a complete nightmare. I honestly don't think I would recommend this to anyone unless they have another person to help them assemble it, because doing it by myself was terrible. I don't think I'd buy this again, I think I'd opt to just spend a bit more money and save myself the trouble personally.

Reasonably adequate room divider
Size: 4 Panel-88'', Color: Beige
I'm reviewing this as I assemble it. Couple things: 1. I didn't expect as much assembly. I've ordered dividers before and they more-or-less came as one unit. Sometimes the panels needed screwing together. These require complete assembly and come largely as three rods: two make up vertical columns and snap together. Another one (called part "C") makes the horizontal columns and you have two of these per panel (one attaches to part "A" and the other part "B"). These parts are metal with a plastic shim. Using the wood screws to attach to part "C" is a real pain in the neck. There's not much holding the panel in place so it's a little tricky. One tactic I've found while I'm assembling that works for the initial connections from parts A and B to their respective "C" rods is to hold the screw in place with a screw driver and then rotating the rod around the screw. This will do a number on your hands if you aren't wearing gloves. This obviously doesn't work when completing the connection. Using a driller driver on this is really near impossible because there isn't anything you can use to secure it in place. You can use it on the first panel, but as it gets longer, it becomes increasingly difficult and because it isn't wood, it's really tight. I considered drilling larger pilot holes but since there are only 4x4=16 screws I need to screw in, I just decided to use my screw driver to complete it. 2. Also related to assembly. When completing the panels (attaching parts "A" and "B" to parts "C" that have the cloth cover on it), you have to be careful that when you tighten that side that it isn't loosening the other side. Because the pilot holes are so tight, you can end up rotating the rod, which rotates it in the same direction as looser on the original side. Having someone hold the "C" rod in place while you screw it in is probably the easiest approach. I didn't have a 2nd person, so I just had to keep flipping back and forth and tightening both sides as I screwed it in. Not the worlds biggest deal, but annoying nonetheless. 3. The way the instructions are written, they seem to suggest building this thing progressively; that is, you do panel 1, then 2, connect them together, then do 3 and connect it, etc. I took a different route that I suspect saved me quite a bit of trouble, and I assembled all four panels first and THEN connected everything together. 4. For the love of God make sure you check that the plastic tip is on the same side for every panel. Otherwise, you have to take one side apart again and reverse it. On the bright side, if this happens, you've essentially bored out the pilot holes to be the correct size... which is having me question if I shouldn't have just bored them out to the appropriate width in the first place. 5. Attaching all of the panels together is also an enormous pain in the ass unless you happen to have an 88" long elevated surface. Attaching the legs either requires you to elevate one side, which will invariably twist the inexplicably cheap material in the bottom connectors... or you can attach them sideways... or you can put this thing upright, having two people hold the panels in place while you use the allen wrench to tighten the bolts on the underside. None of those are particularly great options. NOW on to the utility itself. 1. The panels do let some light through (I didn't believe their advertising, and that was one of the reasons that I bought beige, is that I wanted it to not be too dark). They aren't transparent though, so it isn't that far off from their description. They functionally work great, and keep the mess of wires hidden and when I'm sitting at my desk, actually reflect quite a bit of light into my office. Great! 2. My wife has described these as "the most hideous piece of furniture ever conceived of by man." So it does not have spouse approval factor. Granted, she will seldom be in my office area, so that isn't the end of the world. 3. These are really hard to align in a way that doesn't look a little tacky. There are some plastic connectors but they don't do a bang up job of keeping these in place. Each panel is slightly tilted and it's... quite obvious. I may at some point make my own improvements to these to help make them more level. It's not a particularly expensive product so I wasn't expecting much so it's fine and I'm not going to ding them on the rating because of it. All said, would I buy this product again? Probably not. It's assembly was ~90 minutes which is about 75 minutes longer than I was anticipating spending on this (not including the 5 minute writeup that I'm doing here). But am I going to return it? Also no, if for no other reason I'd be just as annoyed taking it apart and putting it in the original box to return it.

Easy peasy
Size: 1 Panel, Color: Black
Bought this single-panel room divider for my son so he has a little privacy when he has to keep his camera on for online classes. It’s lightweight, easy to set up, and does the job—he can focus without me photobombing in the background. He can feel like he has his own tiny corner office, even if it’s just the basement.

Product really works well & serves it's purpose! Great height & width. It's flimsy, but it will stand still when put in place.
