Sorry if the reviews are hard to find in the shop - you might need to look under another version of it (for example the spare goggle or the Basic kit if you've been looking at the Chronic). Surprised there aren't more - it's probably the single most-used non-drop consumer dry eye product on the market.
For a lot of cases I think it's been eclipsed by the Onyix/Quartz silicone shields because they're easier/simpler to use but for maximal protection & moisture or to help hold lids down Tranquileyes is useful to an awful lot of people. Sometimes it can take some tinkering to get it to work just right for you.
