Harley Benton Fret Rocker

Not all sides are straight, makes the tool redundant really as I don't trust it at all now. It will show frets are level using one angle, and the same 3 frets on a different edge will show high frets. Would not recommend.

On most sides the ends wasn't as flat as needed for this job, If you wanna mess around with a cheap rocker its fine, If you are looking for a professional tool this won't work, you need more accuracy, do not use it as a point of reference for fret levelling you will regret it and it will cost you alot of money!

I ain't gonna lie I didn't find this one precise enough The longest side ain't even straight and the rest could do much better

So I got this sent to me twice now and both of them have this anomaly on the longest side of the fret rocker - this longest side is not cut straight and there is a little metal part coming out of the line, this extra metal bit is exactly at the same spot on both the units I received which is why I guess that its the laser machine that cuts these which has an issue.

OTHERWISE IF YOU IGNORE THE LONGEST SIDE AND WORK WITH THE OTHER SIDES THEN ITS PERFECT AND DOES THE JOB. HOWEVER NOT GOOD FROM THOMANN'S QUALITY CONTROL TO MISS THIS ISSUE.

The second shortest edge is not straight enough for guitar use. If I use it for fret height measurement, there is a danger that I will file/sand the frets too low. I will need to find a completely flat file and hope that I will be able to straighten it...

The edges are quite roughly cut, you can easily see gaps when you hold it against a ruler. Not flat enough for a fret rocker.

I managed to fix the gaps by sanding the rocker on a flat surface.

I started checking for rocking frets on a guitar and noticed that only one of three sides was rocking on the same frets. I then inspected the tool and realized that the main side to use was slightly (but visibly) bent. Argh!
