Review: Works quite well - I do not like the circular nose trimmers. You don't seem to work. The vertical ones are the best but each has its own issue. This one works quite well. The issue is cleaning the blade. You actually have to take it apart before putting it under the water. Other than that it works amazingly well. To take the blade off. You have to pull up the plastic onto one side. Their instructions isn't that great, but I recommend this trimmer
