I use this just about every day. It's the most convenient capo. It does throw your guitar out of tune a bit more than Shubb or G9, but it's more quick and convenient, which is crucial for me. I'm often working with kids and leading services at my temple with my guitar, and it's great to be able to place it with one hand and not disrupt the flow of what I'm doing. No one notices or cares if I'm thrown slightly out of tune. If I'm playing a coffeehouse, everyone is doing their patter while tuning between every song anyway. I have used some of the other capos mentioned in that situation.
