Good Tool, Thoughtful Design
Great quality as far as I can tell. The black and white color scheme makes it much easier to read, more so than a cheapo metal & black one I have. This is far superior, enough that I wouldn't want to use the cheapo one after using this one. Only used it on a few guitars so far but it's been a pleasure (always a pleasure when tools don't get in the way of your work!). It's the perfect size and the included scales and rough figures save me from looking at my phone/computer repeatedly when dialing things in. Nothing to complain of here, it's a good tool all in all.

Simple and great
This worked perfectly to ensure my frets are level. It didn't cost a lot but performed well. Very intuitive. The varying side lengths were important as you move from top to bottom of the fret board. You want to rock it across three frets at a time and obviously you need a shorter length on the high frets and a longer length on the bottom. Great tool!!!

Not the best quality.
OK as an action gauge, but not all edges are flat enough for finding high frets.

All you need and nothing more; price is right
If you are going to concern yourself with fret leveling, you need this - the different-length sides are invaluable for moving around on the fretboard, and you want something that is well machined (no burrs, and, well, straight). Also, this has useful measurements on the side, and the price is appropriately low (you really do NOT need a 'fancy' fret level). Recommended.

Indispensable Guitar Tech Tool
If you build or just maintain your own guitars, you need this little tool. It's a fret rocker for tracking down those elusive buzzes with different length sides to accommodate fret spacing all the way up the fretboard. It is embossed with a variety of measurement guides and mini rulers to facilitate setting up your guitar's relief, action, and 1st fret space. There are suggested string action values for a variety of guitar types. It even has a Fraction/Decimal/Metric conversion chart. It belongs in every guitarist tool drawer.

Well Made, Feels Solid in the Hand. Recommended.
Does the job. Resists bending/flexing by hand. Easy to read the scales. Found a high fret on the first guitar I tried in on. Only one minor complaint. I measured the graduations and found one slightly off. The 5-10 millimeter scale on the short side is high by 0.02mm. I doubt I'll use it, though.

Good for the price.
Work great and straight enough to do the job. Glad I bought it.

Decent quality, reasonably priced, multifunction with string height gauge
This checks a few boxes because it functions as a good fret rocker plus a string height measurement gauge and it is not overly priced like some popular tool brands.

Couldn't find any way of contacting the seller direct, therefore here's an honestly review. This fret rocker needs to be a precision tool to do it's job properly. See photos, quite frankly it's a disgrace! When I tried it on a decent guitar, every fret appeared to be rocking, and not in a musical way. I immediately thought, something isn't right here! After checking the rocker on a known leveling tool, it became apparent this was not suitable for purpose. Do not buy this fret rocker, it's a piece of crap! I should have known better, you get what you pay for!

Edges are dead straight and measurements are accurate. Much easier to read the measurement markings on this versus using my silver pocket ruler with thin black markings.
