I have also tried virutally all of these keyfinders. My last set I owned were TILE.
The absolute best keyfinder I have ever found was the PEBBLEBEE Keyfinders. I just purchased 5 more. They just came out with a new generation.
Next time you do a review, you should include them too. Having owned them all and having tried out all the software suites myself, I can honestly say, They are better than the TILE. The software on your phone that manages them is just plain better, and it seems is more accurate when tracking down the lost item.
