We first checked the battery analysis on each phone and determined that was not the problem. Good luck with your decision. Beads all different shapes & sizes. Not that set up was difficult it would just be a nice addition! I do like the light idea from the previous review and will consider that. I dont leave a lot of reviews. Only down side is that they are so light weight they tend to slide off my foot a little. I do believe that for some reason I got a defective pair ( and I dont believe that is typical of this brand) but other than the stitching issue they appear to be of good quality and very warm and cozy! The product is very hard and not similar to other relaxed boots. It is a little difficult to remove but but not too hard if you use a lightening cord to push it.
