These Trimmers are a piece of crap, they take forever to cut on they don't cut like shown on the video I try to contact someone they told me to make a video of the issue and contact them back each time unsuccessful with a return message. I took him to a barber supply store to see if I can get the blade sharpened they told me that there was nothing they can do about these and that I should try to get my money back because a lot of people were buying these are not being successful at what was displayed on the video. It's sad SMH, I would greatly appreciate a full refund and you have your product back...
