Feature:
Does what it's supposed to do. And only a dab is needed. I spray a very small section of the back of my neck with the stuff, and then take a clean cloth and rub it up and down the guitar neck.

Quality:
It's good quality stuff. I've never had any issues with it discoloring my finish or anything like that.

Value:
I used a similar product before that came in a tube. I don't remember what it was called, but finger ease is a better product in my own estimation.

Desirability:
are spray cans sexy?

Sound:
This stuff rocks. And it lasts forever. I bought one can 10 years ago, and I just now ran out. I figure if I buy 4 cans of the stuff, I'll be good until I'm ready to start collecting social security. Typically, I use lemon oil on my rosewood fretboards, but only after I've cleaned them very well with rubbing alcohol. However, I love the look and feel of a high gloss finish on maple. Problem is you can get tacky/sticky issues. That's what I use this stuff for. I use finger ease on the back of my guitar necks, and it plays and feels wonderful. Try it, you'll like it.

Ease of Use:
Couldn't get much easier.

Support:
Never needed support.

Overall:
It's good stuff.

Feature:
It helps with the clammy or sticky feel a guitar can sometimes have, based on humidity, temp, your hand's chemestry, cleanliness, etc. I have used this product for 20 years. A can lasts for years. I hold it in my right hand, and spray it to hit my fretboard, left hand and back of the guitar neck in one brief spray. It is usually good for a full set of playing(45 min to an hour).

Quality:
every can consistently good, lasts a long time.

Desirability:
I always have this product sitting on top of my amp, in quick reach for all practice sessions, and gigs.

Sound:
Sound is not really the issue here, it is ease of play, which improves your music, but it does not actually change tone or pitch.

Support:
Never had to deal with them.

Overall:
All good, no negative comments

Value:
I paid seven bucks at a guitar store. Not worth that much!

Sound:
Cuts down on string noise

Overall:
good product to cut string noise and makes it easier on callouses. If you get it on your pick fingers, its almost impossible to keep hold of the pick.
