I?d give it three stars for being a bit pricey one not the greatest design, however relative to other versions it could be five stars. There are elastics inside to hold bottles upright and a firm bottom that folds out unlike most bags I?ve purchased. Battery:This is the only plus for me. Which it does work there too but as you can see in the pic it works on my 1st piercing. They did send out another product but it was the same and as I had been away I missed the cut off to send it back. Love them very comfortable, get complements everywhere I go, if I?m no wearing them They are I?m my bag as back up, I like them so much I ordered three pairs. The shoebox said US size 7 which is what I ordered but the actual shoe itself said a size 6 it was too small therefore making it very uncomfortable. Definitely used it for something besides shoes but it works great! Others wont connect. I use parmesan cheese bottles to hold; nuts, bolts, washers etc.
