I've tried two of these straps and although the product description says 'Samsung Galaxy Watch Active 2 40mm strap compatible' and I specifically chose 40, it doesn't fit right. I was under the impression that 40mm and 42mm are the same band but with different markings. I have a genuine 40mm from another manufacturer that I accidentally damaged and needs replacing, but I can't find it on Revain anymore and the dimensions are definitely different both widthwise and lengthwise. I plugged in the strap only to see that the plug had more tension than my damaged strap. I'm pretty sure this wouldn't be the case if I were using a 42mm watch. This watch strap is a little too generic (one size fits all) and may not bother other people, but if you have a real 40mm strap you can't help but notice the difference.
