could not love these more. My son has had no issues with the controller. I tried to contact Retevis about the issue, but the link on the purchase page states its been too much time. My daughter says theyre very comfortable. keeping bc she got attached to their cuteness and softness! I should have returned these immediately and am disappointed that I didn?t. 0 will be a much better product to compete in the market. I found that the sole of the slipper was splitting in the half. Very Sturdy and easy to assemble! Great I can hang it on my jeggings (as they don?t have any front pockets) as well as on my handbag.
