Customers say

Customers find these servos to be good value for money, with positive feedback about their durability, with one customer noting they can withstand hangar bumps and knocks. They appreciate the metal gears and decent appearance, and one customer mentions they work well in 60-inch slow flyer model airplanes. The functionality and rotation angle receive mixed reviews - while some say they work great, others report that some units don't work at all, and several mention they only rotate 360 degrees instead of the advertised 180 degrees.

Bait and Switch - Not getting what you paid for.
Pictures show a nice servo with metal gears and metal bushing/bearing. Although you get metal gears, you don't get metal bushing/bearing. Attached pictures of what I got and what is being advertised. So, there is a lot of slack and of the 8, 1 didn't work at all. Return.

    If your tired of the little blue crappy cheap servos that fail or strip gears - these are the best upgrade for cheap
    The servos are strong enough
    The only thing weird is the screw that holds servo arm on is now a tiny machine screw vs the common wood type screw - they only provide one of these per servo but provide two small wood screws
    So if you lose the tiny machine screw for the little actuator arm your done can't use a wood type in it
    They need to provide at least 2 per servo
    Other than that fantastic

    Please READ. Note you are purchasing small metal geared servos that are for a really low price. It will be expected that some may come in defect. But for the price and quality of the servos you can’t do much better here on Amazon atm. So as far as I’m concerned well worth the $$ for how much and the quality you get. These servos can easily operate a larger scaled plane with little to no effort. If your looking for quality and durability and reliability your welcome to look for more expensive servos. But honestly is it making that much of a difference unless your building an expensive project, then I wouldn’t suggest using the cheapest items you can buy.

    Love them!!! Super tough, highly disposable if they fail. Ive had 2 out of 16 fail on the bench before use. I run them for about 30 minutes on an oscillating servo tester before I put them in a build. Some fail in seconds some fail after 5 mins and usually the open ore close 100% when they fail. Just think.... cruising along doing aerobatics, then BAM an aileron goes 100% wide open and then you have a bad crash into a vehicle breaking the windshield... bad day for a few people!
    Ps that never happend but it could if you dont test them first!

    Just received eight servos. Cycle tested 500 to 2500 pulse width (0 to180 degrees), no load, on 5 volt power supply for at least 30 minutes for each servo. All passed OK. They will meet my needs.
