These tuners are an excellent replacement for lower quality vintage-style tuners. I have used these on Squiers and the Harley Benton TE-52, and they are usually an easy fit. They turn smoothly, sometimes they can be slightly stiff though. They keep tune well, much better than the default tuners on Squier guitars.
The screws which are provided are quite large, much larger than the screws found in most cheap guitars for some reason, but I usually use the original guitar's screws anyway to solve the problem. I can definitely recommend these tuners and they are worth their price.
