12PCS SG90 Micro Servo Motor, Dorhea Mini Servo SG90 9g Servo Kit for RC Helicopter Airplane Car Boat Robot Arm/Hand/Walking/Servo Door Lock Control

These are typical, no better or worse than others. All 12 that were shipped work perfectly. I do like that the plastic gears will tolerate a bit of "grinding" if the load is too heavy, but otherwise these are typical but very good for the price.

I used the servos to control model railroad turnouts and so far they are working well. They came nicely packaged in and secure box. I tested all of them and they all worked and are working well on my model railroad. Good product, good price and they arrived on time.

Have tried to use as a replacement for aileron and find that I have to replace both because it operates the same direction as the old unit, on the other side.

Given what the price is per servo they are not too bad. Just expect that you will get a couple that are bad.

Servos are great other than two of them did not perform properly due to the servo glitches and operate when they want or not function at all. The rest worked as advertised. Good value for my money.

SG90 Micro Servos should not be expensive. These are an excellent value. Highly recommended.

Funcionan bárbaro, son lo que son!

These are not great quality servos. From my experience they have about a 5-10% DOA rate, and they also do not last as long as higher quality servos, even if they are not DOA. However, they are cheap as heck. If you need a bunch of cheap servos to do the job of cheap servos, this is a fine deal. $1.58/servo is throw-away money, but these are throw-away servos, you get what you pay for. If you want high-quality, precision servos for critical applications or use in twitchy or valuable flying models, look elsewhere.
