love it!!!!!! if you have a problem with watch bands that never fit this one will fit (i heard 10"+ and that sounds reasonable; i have 8.5" and could have worn this over a light jacket.. plenty of room)... the double locking clasp is great, quick on off, love the color, 20mm fits Samsung 40mm Watch 7 fine and doesn't bind up.. plenty of room. in addition to adjusting the watch straps by cutting, there's a 3 setting adjustment on the clasp. comes with tools to remove standard (non quick) watch pins.. nice tool which i had that a long time ago. loved it so much i immediately ordered 2 more for safe keeping thanks!! excellent

This watch band is a full 20-cm long when ordered and is adjustable by cutting off ½-cm segments until it is the right size to fit your wrist with the watch attached. The butterfly clasp holds firmly and has a locking tab that keeps it from popping open unexpectedly. However, once cut to size, this band is not adjustable for accommodating fluctuations in wrist size. So sometimes it is going to be too tight, while other days it may be too loose.The kit comes with extra spring bars for both the strap-to-watch attachment and also for the strap-to-buckle attachment. The kit also comes with a tool that has a split flat end (to pull on the spring bar of your old watch band) and a sharp end to push on the end of the spring bar in the buckle attachment. The spring bars for the watch end have a pull tab that makes it super easy to pull back the spring to insert or remove the band from the watch. The spring bars for the buckle are not so easy to remove or insert, as the pin has to be pushed in until it fits within the edges of the buckle.The instruction guide that comes with the band does not show the same type of band. Although the same butterfly buckle is used, the band in the instruction guide uses a pin fastener (like a belt buckle) which has an overlapping end and holes at various points to adjust the length. What you actually get (and is shown in the Amazon listing) is a band with segments that have to be cut off in order to resize to fit your wrist. The problem with this is that there is no overlapping end - you have to cut the band to the exact length that is needed, and there is no adjustment beyond this (for days when your wrist swells or shrinks slightly). Once cut to the length that you need, the spring pin goes through the last segment of the band and clips into the retaining holes on the edges of the butterfly buckle. Also, if you cut off too many segments of the band, there is no fixing it. So be careful how many segments you cut off and size check it often. As it turns out, I wish I had left one extra segment on the band - it fits, but most days leaves an imprint of the buckle on my wrist.Once sized to fit, this watch band is attractive looking and smooth. The band fits comfortably on the wrist (so long as you haven't removed too many segments) and doesn't pinch the skin below the buckle. I do like the extra locking tab on the buckle which ensures that it doesn't open accidentally.Overall, this band feels very solid, and the pins seem to be strong enough to hold the watch firmly. My biggest complaint is that there is no adjustment once you have fitted it to size, so it isn't adjustable to occasional swelling or shrinkage of the wrist. And it was quite challenging to press the tiny ends of the spring bars into the buckle.

To start, I gave four stars only because I'm not sure how I feel about the rubber material the band is made from yet. There's nothing wrong with it per se, I'm just very used to silicone or resin (or fabric, but that's certainly an apple in a basket of oranges). Installing the band is very easy, just like any strap with a quick release pin and it takes a few tries to get the length just right. I made sure to take a little from both ends to keep the taper as equal as possible. Depending on your wrist size and preference, you may have one strap be one "section" longer than the other, but I suspect this is normal. In any case, don't hurry! The clasp is quite nice and has a standard "push-push" release accompanied by a fold down buckle keeping everything nice and secure. The clasp ends of the strap are also secured with pins, so no clamps that could pull off here. I'm not 100% sure what "fluororubber" is, but here's my best shot... It's not quite as supple as silicone, but it's more supple than a resin band. The tactile feel is very smooth. Smoother than a silicone band, which tend to have a little more friction. Visually, the yellow band has an ever so slight "chalky" appearance whereas a resin band reflects more light. I tried to get the best representation in the photos. It's not bad at all, just different. Finally, I really liked that it came with some extra pins (in case you catapult one into space only to find it years later while cleaning that one spot) and it also comes with a very useful pin tool. Nice.

Got a few of these because the price is unbeatable. Clasp was unexpectedly high quality; milled from a solid piece of metal rather than a cheap stamped clasp.Fantastic watch strap. It will fit any sized wrist, trust me... I have an 8" (200mm) wrist and there were like two extra inches to spare.If you've never had an FKM rubber strap, TRY IT.... it's WAY nicer than the typical cheap silicone. It's slightly heavier, more comfortable, and feels less sweaty. There's a reason why luxury brands use FKM rubber and not silicone.Some assembly is required; you will need to trim it to size. All very standard for this style of strap.
