Okay so like most of us keggers I was looking for a simple way to see just how much was left in my keg. So I saw these SmartStrips and for 2 bucks I figured why not.
The strips are okay. This is the deal, the stick pretty well, I put them on dry warm kegs and moisture laden cold kegs, and both times they attached and stayed attached with no problem. They are supposedly removable, I don't intend to do that, however it appears that claim is true. The temperature feature is just ok, but I don't really care because I have a thermometer in the fridge already. Finally the reason I wanted them, to take a quick look in the fridge and see how much is left in each keg... To start they actually do work, it will tell you how much is left in each keg, the neg part is for that to work you have to run a warm rag over the gauge on each keg each time you want to see the beer levels. I have mine in a stand up fridge so it isn't too hard to do, but kinda annoying. If you were in a chest freezer, I can see this to be nearly impossible without moving a bunch of stuff.
Okay there is my way to long review of this $2 item.
