My only complaint would be that the metal is a little thin, but these are really good for the price. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars They do the thing *by M***E on Reviewed in the United States on March 10, 2023* These are what they advertise. Already owned a more pricey action ruler and this is equal to it. Used the radius gauges to do 2 nuts. Pretty much everything you need to measure for basic setup if your bridge saddle has adjustable height per string or if you want to replace a nut. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/188673461-xtremeamazing-9pcs-understring-radius-gauge-luthier-tools-and-4pcs-guitar](https://www.desertcart.co.uk/products/188673461-xtremeamazing-9pcs-understring-radius-gauge-luthier-tools-and-4pcs-guitar) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-06-08*
