ToneGear The String Cleaner Cleaning Tool  

I bought The String Cleaning Tool because a friend recommended it. The first thing that I noticed is that it is made out of plastic. The microfiber cloth on the inside that clamps down on the strings was also cheaper quality than what I expected. After I clamped it down on the strings of my acoustic, I slid it down the neck from the soundhole towards the nut and it worked fine until the 5th fret. At that point, the plastic side started to scrape against my frets. That's the area where the strings need the most cleaning, but this tool couldn't clean very effectively there. A thinner design for this tool would be ideal.

Low quality materials were used to make this tool.

I wouldn't recommend this product because of the low quality. My next purchase will be a certain cloth that's used to clean brass instruments. Dan Erlewine recommends that for cleaning strings.

Easier and faster cleaning strings. Works as expected; doesn't leave pieces of cloth muting the strings.

Good, for a simple constructed device.

Price is ok, for a simple constructed device. 

I don't change strings for every venue, so the better the string cleaning, longer life will have my strings.

It cleans the tops of the strings which any cloth can do, but it gets underneath the strings where the gunk has more of a tendency to build up and get on the fretboard.  Normally that stuff's a pain to get to.

It's cheaply made, which is no surprise since it's ten bucks.  Just be careful with it (make sure the cloth doesn't snag on the strings when inserting it, etc.) and it'll last plenty long.

When I use it every once in a while, the string regain some of their brightness.  I'd say that's an indicator that the strings are going to last longer with this.

Overall, I'd really recommend it, especially if you have a tendency to cover your guitar in what looks like alien biofilm like some people I know.
