I own and use my SteamBuddy often. It took a few minutes to actually figure out how to use it and master it so I understand why some people might think it doesn't work when in reality they just didn't know how to work it. A lot of people reported on this board buying it, loving it, and getting more as gifts.
And I don't say that about just any of their products either. I have little to nose use for Zorbeez and Hercules Hook, for example. EZ Foldz I have and like, but it's not exactly life changing lol.
