I bought these tuners for a "partscaster" guitar - that is, a bolt-on neck electric guitar consisting of parts from a variety of sources. For my projects, I don't need a $100 set of locking tuners. I've tried ultra-cheap tuners, and they were junk. (In fact, I bought these tuners as replacements for a set of ultra-cheap tuners.) These tuners hit that sweet spot for me where the quality is good enough for my amateur playing and the price is manageable. I just installed the tuners, so I can't say anything about longevity. They looked good and felt solid when I installed the strings and set the intonation. I recommend these tuners as an upgrade for very inexpensive guitars and as usable tuners for project guitars.
