Smraza MG90S 9G Micro Servo Metal 6Pcs Micro Servo Motor Kit for RC Robot Helicopter Airplane Car Plane Boat Control, Compatible with Arduino Project (MG90S Metal)

Very nice quality small servos! They arrived well packaged. Every servo is individually packaged in plastic bags, then inside a heavy cardboard box for best protection. Each one is complete with it's accessories and mounting screws. The cables are about 9" long. The gears for each servo looks high quality which gives me a good expectation of durability. I'll test and used them so, I can give a better functionality feedback later on.

Works fine.

So far they're GTG!

Got the ones with metal gears thinking they might be of higher quality. Only four out of six worked when I connected them. The other two had no response at all.

These servos are made with high quality material and offer great performance. Worked smoothly with my arduino. I'm planning to use them with my mini robotic arm project, they have enough torque to handle it. If you're looking for a durable servo that works with a variety of boards like arduino, Raspberry Pi and others, look no further! I highly recommend this servo.

Two out of 6 not working, a couple of them broke with in short usage. Sub standard and would not recommend to anyone one.
