Can't blame the product...
So the balls are pretty nice. I suppose I knew that 25mm was for advanced users, but decided to try them anyway. Put them in and basically nothing happened,  couldn't feel them at all. Walked around with them for an hour and they just stayed up there, somewhere.  Couldn't birth them out but was able to squat and use my finger to get out. To small and to lite, need to be heavier. I've never had kids and do a lot of yoga so I thought maybe I could start with these... lol or maybe not. On to the shelf for hopefully a later date.
