I had some bad luck with the 995 T-Pro digital servos a few years ago, they were really bad, so I was kind of gunshy about trying these ones.
Well, I've used about 20 so far, with no issues. All have been fine right out of the box, they are just a decent, powerful, accurate standard servo, with a nice quiet geartrain, suitable for most uses, with a nice complete package of horns and mounting hardware. I have put quite a lot of flying on them with no issues at all, I'm very happy. I build a lot of planes, and I am always looking for ways of fitting them out without spending so much, and these really help. They work the same as my Futaba or JR standard servos, no issues.
