I got it off of Ebay. I tried it out on my 4 month old yorkie who needed a haircut bad.

I didn't want to send him to the groomers because I'd rather just be able to do it at home myself. Save some money too.

Well, they actually work pretty good. And they are easy to use too. I wasn't sure about them, but they have really good ratings. I am really happy I decided to get them. And he actually doesn't mind me cutting his hair with them since it isn't loud and it just feels like I am brushing him. If you have a doggie who doesn't like the sound of clippers, I would suggest these.
Does anyone else use these as well?
