Yes I would recommend this trimmer. I’ve had a lot of trimmers in the past and this one is definitely the best. It stays at the length you set all the way through the trimming whereas some I’ve had in the past do not. The battery length is good too.
It comes with a two pin connector and can be used while plugged in, but there is no need because the battery on this trimmer is long lasting. I don’t need to charge it for at least a week a time sometimes more. It has no hair collector.
