Great ingenious product!
The material is plastic/nylon it feels like it will last, it's pretty light also. It can be attached to aero bars in different ways, if you are overly concerned that your bottle could get "ejected" it can be mounted the other way with the opening of the bottle facing you. The only thing may wear down are the zip ties which can be found in any hardware store cheap.My wife have used it in two tris with no problems whatsoever, her regular team bottle water fits tight. I'm getting one for me too.

Other than that it works fine.
It attaches with zip ties? really? Other than that it works fine.

this thing is awesome - I get questions all the time on where to buy it. We have garmin 810s and its very secure. My wife took a pretty hard fall on the bike recently (she was largely fine) and no issues - computer stayed secure.

Good enough.
This is a fine mount, but the garmin mount doesn't fit any Garmin I have even with the available adapters. The straw sticks up in the air, costing some aero energy, but you can stick some Velcro on the frame and around the straw and push it down. There's probably a less expensive solution to a BTA hydration system, but this is easy to install and convenient and lightweight.

Defective plastic
The piece that the garmin mount clips into looks defective. The garmin clips in, but it won’t be long before my garmin launches off my bottle cage…. See pictures, the clips are not uniform. One piece has an overhang and looks like it is faulty plastic that is not very strong at all.

Proven
Avid triathlete here. The reason why I chose this drink method over the behind-the-saddle holders and even the original bottle placement on my seat tube is that between-the-arms solutions have been proven to be more aerodynamic. In my very cursory wattage comparison, I found that it saved me roughly 6 watts over a 5 kilometer flat segment that I was using as a testing ground. That is 6 watts savings over the behind-the-saddle option that I was using previously.

Missing parts
Received today, seems like an ok product but was missing the drink tube clip and non-slip Velcro plug strap. Sloppy sales IMHO.
