I got this band as a replacement for a Formula 1 Tag Heuer.One notable feature of this band is that it has a raised channel on the underside of both straps near to where they connect to the watch. This is presumable some sort of sweat/water conduit.Beyond that, it's a simple and clean-looking black band. The straps easily and quickly connect to the watch. They feel secure. The rubber of the straps is on the firmer side. Not exactly "hard" plastic, but don't expect a flexible, rubbery silicon style band if that is what you are looking for. Personally, I like the band's slightly stiffer quality.For the price, I can't think of any reason not to buy this band. I'm a few months in and it feels like it will last a long time.

High-quality, comfortable, bright, beautiful!

I like that the silicone band was reasonably plyable, light weight, a real rubber look-alike, and the best factor was the price. I believe anyone who fits it on a Rolex, or a "knockoff" will enjoy it.

It's everything I hoped for. Fits perfectly.

The band is discoloring from rubbing against my shirts and sweaters. It looks very dirty.

David Hancock
Its nice looking and very well made. Looks leather but bends like silicone.

This is a review of the WOUKUP Silicone Watch Band, in 20mm, orange, and black buckle, with an ASIN of B0C1RPDF5P.Short version (TL;DR) - Negatives: Ventilation channel grabs arm hair. Stiff. Mildly stinky when new. Positives: Well molded. Ventilation scheme actually works.Long version …For me, this is a 2.5 star product, rounding up to 3. It’s not one I stuck with using day-to-day, but it’s better than it seemed initially. The biggest issue is that their attempt at improving ventilation, while it works, also makes the band rather uncomfortable for those with wrist hair. Oh, it’s also not good for people with small wrists, but they’re up-front about that in the stated dimensions.Negatives:* Ventilation Channel Grabs Arm Hair - unless you have very minimal arm hair, I suspect this will be an issue for you, too. I think my hair level is about halfway across the spectrum between an Olympic swimmer and Robin Williams, and this band was giving me surprise tugs and rips at the weirdest times. It wasn’t that frequent, but it tended to be in bad situations. As such, I see this as being the biggest issue.* Stiff - between the type of silicone used and the ribs for the ventilation channel, this isn’t very flexible, so that’s another comfort-related strike against it.* Mildly Stinky When New - a lot of molded silicone stuff stinks a bit when new. Unfortunately, this was above average, though that’s not to say it was anywhere nearly as bad in that regard as the  Barton Tropical 2.0 band .Positives:* Well Molded - they implemented a relatively complicated design rather well. Based on how well the keepers fit the strap, they also adhered to reasonably tight tolerances.* Ventilation Scheme Actually Works - for all its arm hair grabbing and ripping, I found the ventilation channel really did keep my wrist from getting as sweaty under the band. That said, personally, I think I’d rather have my wrist sweat a bit more in exchange for not having the sudden shock of a hair getting yanked at random times, but you think differently.In conclusion, if you have reasonably large wrists that aren’t particularly hairy and are concerned about sweat beneath your watch band, this might be for you. Otherwise, I suspect you’d be happier with a more conventional band design.
