I have the LDO Rev. C kit, and it is rock-solid. They’re releasing the Rev. D kit soon, and I can only imagine that’ll be even more refined. I printed my own parts using a combination of Phaetus aeWorthy ABS-GF and 3DXTech ABS-CF.

If your printed parts are good-quality, you follow the directions precisely, and stick to the kit (no mods beyond the LDO-provided ones), I see no reason it shouldn’t provide years of trouble-free service.
