I've been using the Braun BT7520 beard trimmer for a while now, and I'm very pleased with it. The device feels sturdy and fits comfortably in the hand. I didn't experience any skin irritation while shaving, which is important to me, especially with regular use.
During testing, I noticed that I appreciate that I can simply clean the trimmer under the tap. This makes cleaning much easier. The dial on the trimmer makes it easy to set the desired length, and the slider keeps it securely in place. It even comes with a template so I can keep my beard even on both sides.
I've also noticed that the battery lasts a considerable amount of time, up to two hours. I can store the trimmer neatly in the included carrying case, along with the various attachments.
