The Machine is very flimsy and not sturdy. Needs 110 voltage cord and not phone charger port. Carrington bag doesn't have a port to plug it in. I should have done my homework and bought a better model.

Your service is awesome. I can’t say the same for the US Post Office. You answer questions quickly. Your prices are really good. And the quality is terrific. We’ll be back if we find we need anything else.

Cost, short delivery time

Worst company I've ever dealt with. This company cannot be trusted as they are scamming people. I ordered a machine on the 29th of April and they only sent me accessories and not the machine. I've sent dozens of emails and called asking to cancel my order and they keep running around in circles. I highly recommend you stay away from this company
