In one of the blocks was a small, freely moving drop of solder, which still could lock the findings of the chip and put the block out of order. We'll take that as an exception. All blocks work according to the description, very cute, remind small computer mice. It is wonderful to glue on the stomach, take a beer, lay down in the chair and watch hohma from the gym. Thank you to the seller, manufacturer and delivery service. I recommend the product.
very powerful don’t know if it will leave results as it doesn’t stimulate the muscle but it feels like you are being zapped multiple times
