The 7mm also slipped on & off the 10mm tube. So I did a return through Amazon and got another set. Same problem with the 20mm tube.So yeah, I'm not expect the best quality for these cheap tubes, but I do expect them to know how to use a lathe properly to cut a proper M42/0.75 thread.Obviously, I'm not going to attach my $1000 camera to these tubes.Also, these seem to be anodized rather than say powder coated. I don't really care which, but the inside of the tubes should be matte not glossy, so even the tubes that are cut properly aren't that great. --- ## 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.hr/products/72696884-telescope-t2-extension-tube-kit-for-cameras-and-eyepieces-length](https://www.desertcart.hr/products/72696884-telescope-t2-extension-tube-kit-for-cameras-and-eyepieces-length) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-07-19*
