Perfect for large wrists
Wow! A watch band that actually fits large wrists, is comfortable, and well made. Who'd have thunk it :) Seriously, EVERY watch band I've ever gotten has been at the last notch, if it even fits. As much as I love the TREX-2 the watch band sucked. I came across this and immediately attached it and put it on. ABSOLUTELY LOVE THIS!

Comfortable and durability
Best replacement band for trex2. I've tried 2 other types and brands. Silicone, rubber, plastic replacements didn't last 3 to 4 months. This fits very comfortably and easily adjusted to eliminate gaps tomeasure accurate heart rate went needed. And, is very durable. ***Update*** I removed 1 star because the velcro is not long sleeve friendly. I've noted my right sleeve was fraying and found out it was from the velcro on the watchband.

Band is good..tool no good
Does not work for the amazfit t rex pro. The band itself looks like it is of good quality better than the original..but doesn't fit! The tool as well is the wrong fitment for the screws on the band..they are a torx! Update. Returned the 1st band that didn't work. Received the new band and this one works perfect. The tools that come with it do not work..But the band itself is awesome and seems to be good quality. Fits great order the middle size which fits my 6.34 wrist. Has about 3/8 of velcro showing or to adjust and make tighter.

The Best Strap for Amazfit T-Rex 2
I was right on cusp between a large strap and the smaller one, I ordered the larger one. After I added some additional Velcro, the tab secured better as it was too long (no fault of the manufacturer). The strap comes with a tool to unscrew the posts that secure the strap; watch the install video and you will be fine. This strap is comfortable and you barely realize you are wearing it for the fit provided. Very cool design and vibrant color.

2 year review
I've had this watch band for about two years now, so I can speak for at least longevity on mine. This is incredibly hard to keep clean. It harbors whatever yuck you have on your skin, collects dead skin cells like there's no tomorrow and always has a slight smell. The metal is also starting to get worn down and the black coating is flaking off. The edges of the cloth are starting to unravel, but overall it's pretty intact for two years of abuse. I can't use the silicone bands personally since I had a reaction the factory one., but unless you want a yucky smelling arm band I would try something else.

Buyer Beware
I ordered the large band for an Amazfit T-rex Pro. Initially, I was impressed with the look and quality of the band itself. However, I was quickly disappointed to find the tools provided will not fit the watch band screws. They are too small and the wrong type also. Fortunately, I had a tool set from another band and was able to use them. I also noticed that the recess in the band for the screw is deeper than my original band, so the screw does not center once installed as seen in the picture. It will float back and forth and stick out. This is not critical, but something you may want to know. I'm very disappointed that there are numerous complaints to this specific issue and the company is not addressing these concerns. Once I had the band attached, I can honestly say it looks great, is comfortable, and was the correct size for me.

The strap fits well with my trex ultra and is of good quality. I did not have any issue replacing it using the provided tool. Overall I am very satisfied with this product.

I've never liked neoprene bands, and the original one on my watch was no different. This band was the PERFECT replacement. Two things though - first, make sure that you order the right one for your watch. One has a full length attachment to the watch, the other (the one I ordered) has a U shaped attachment with a gap at the 6 & 12 o'clock positions. Second - the 2 little screwdrivers they send are junk. I had previously ordered a regular nylon band with a buckle and the screwdrivers were a slightly better quality, so I used those instead. You could always take it to a watch repair place and I'm sure they would attach them for you for a couple of dollars.
