This device does what it should, but could do it better. So, it removes large pellets, but the "fur" (you know, decrepit threads) remain. Eventually you get rid of globs, but the fabric does not look new because of this. If it was sharper it would probably work. What I do like about it - is that it's AC powered (it was my criteria while choosing), definitely, batteries won't last long. Would I recommend it to a friend or buy it again? I would lurk for some brand that does it better, so no. But AC powered only:)
