The spring is very robust.

Strong spring that good start

Spring is strong but I don't get tension on all 6 strings unless i maneuver it a bit

The spring is really hard, which makes for a solid grip on the neck and an even fretting

The spring feels a little weak and sloppy, but it works for now.

It really has everything that one could ask for in a guitar capo - it's a quality well-made tool that isn't going to fall apart any time soon; it has a strong spring, so it grips the neck and strings quite solidly; and it's easy to open up and clamp on the neck

I've only used this a couple of times and already I feel like the spring is losing some of its snap.

so it doesn't scratch the guitar, and a good tight spring to crimp the strings.

It feels like it was made of much better quality plastic than some of the others I've owned, but I'm not quite comfortable with how strong the spring is.

The spring on this one is even stronger that the one that I was using before and it hangs at least a half inch off the edge, so you can be sure that it's big enough for all guitars

The spring is just not strong enough to keep the strings from buzzing

It is firm and the spring is nice and tight

Strong spring on this one, but know that this unit is straight, and you may have issues on a deeply radiused neck.

It is a bit chunky but the spring and pad on it are very nice

The spring is very strong

I don't feel the spring is strong enough to do the proper job.

The spring is so strong it may even be work for a 12-string guitar as well

The spring feels a little weak and sloppy, but it works for now.

It's not the strongest spring (so great for weaker hands as well), but definitely suitable for classical guitar.

It's think, hard to maneuver while trying to move it to a different position, the spring makes an annoying noise, and you literally need to be EXACTLY precise where you place it on the fret board, otherwise you'll just mute either the low E or high E.

The spring isn't strong enough to bar all the strings leaving a buzz.

Weak spring, has trouble pressing the strings down, you know, the main purpose of a Capo...only paid $2.50 for it, guess I shouldn't be too surprised

Has a great spring

The spring is still strong

Spring could be a little stronger

It holds the strings down, just like it's supposed to, and it's got a nice tight spring on it.

It seems be well build and the spring on it is terrific

The spring is nice and heavy and the crossboard presses on to the fretboard evenly as it should

The spring is plenty strong enough to hold down all 6 strings with no problems

The unit feels pretty sturdy and it has a strong spring

Keep in mind it is very important to fully depress the spring when moving the capo up or down the neck

Came early and easy to use cheap as well i highly recomend
