If you're like me and you like to set your neck as close to straight as possible, this is the tool to get you there with minimal fuss. I already had a notched edge for guitars from another more expensive brand and decided to give this product a try as it was half the price of the other brand's equivalent:
Pros:
* Nice and chunky with a good weight to it - you won't be bending this thing by accident.
* It is in fact straight! I checked it against some other straight edges and there are no visible variations.
Cons:
* Has lots of sharp corners. Compared to the other brand's product, the corners are noticeably sharper; while both products require a certain degree of care when handling around an instrument to avoid leaving scratches, this one will definitely punish you harder should you have a moment of clumsiness. Some careful filing will likely fix this.
Ultimately I'm happy that I purchased this product, yeah there may be an objectively nicer product on the market but you really can't beat the price of the Harley Benton, it does its job and it does it well!
