no surprises [SEP] this is my second beard trimmer previously had a that was powered by aaa batteries was very underpowered and i stopped using it the norelco trimmer works much better it is more powerful and somewhat bigger i like that i can plug it in also so far after trim jobs the batteries are going strong without a rechargethe turbo vac works fairly well some hairs endup in the sink but i expected this quality is good the adjustment for cutting length worked ok my only beef is the filter cup that hold the cut hair is a little clumsy to work with it is plastic so you need to be careful when sliding it back on not to get it jammed or stuck
