Very nice capo. Works easily on both electric and acoustic guitars. It has a very good build quality.
Pro: Very quick to apply and remove the capo. You can apply the capo with one hand if you want. It seems that their spring system really does work, I find re-tuning after applying the capo is minimal.
Con: It's expensive compared to standard capos.
Conclusion: If you use a capo regularly than this is the best choice in my opinion. If you don't use a capo a lot or you leave it in a fixed position then a cheaper standard capo is fine.
