If you use the sterling mag now, I highly recommend these

I recieved an open box and used item ! with some finger prints and some dirty stains on it, I paid for a NEW item man !!! Received standard trimmer rather than the t-cut which is shown

I do wish they would charge while in use, but it has not been a problem yet

Very good I use these as my edgers in a very busy salon

I was far from happy with this purchase because even though the add says it could be either the t cut or pro model it doesn't say that the heads are different sizes and that the t cut model doesn't come with a guard where as the pro does

I would definitely buy them again
