Bests & Worsts Reviews from Amazon

I had ordered MANY of these units over the past several years - at the time, they had SMALLER beads inside that changed from blue (dry) to pink (wet). The small units would dry in about 12 hours, the larger units about 24 hours. These latest units have very large beads that change from a yellow-amber color (dry) to a deep green (wet). I have had the unit plugged in for about 4 days and it is STILL dark green. For some reason, it will not dry the beads. I do not know if it's because they made the beads so large that, once saturated, they simply cannot dry out, or if there is another reason. If I do order these again, I will NOT order the large bead units - I'll either order small beads, or smaller units that contain smaller beads. I tried to find merchant feedback on this, but since it's handled by Amazon, I do not see a place for an inquiry. # # # # UPDATE! I actually left a unit plugged in too long, trying to dry out the large green beads. I finally decided to hang it in the closet, just to see what would happen. Well, apparently because I left it plugged in for about 5 days, it must have weakened the glue holding the unit together. The plug came out of the unit while hanging, the unit fell on the carpeted closet floor and broke, sending the beads all over (and there are a TON of them). But, at least I was able to see that the beads INSIDE the unit were dry, just the green beads on the viewing window were still green. The problem is still that the green beads (which are the indicator of "wet" or "dry") are still green, so there's no practical way to use them. If you can't tell whether the inside beads are dry or not, it's useless. I guess you could try to keep track of the dates, but that's NOT how they are supposed to work. They just need to stick to the smaller beads, I guess! So my conclusion is the same - go for the smaller units/beads.
