"Rating is based on value. These are inexpensive plastic servos and likely will not withstand long term heavy use, but that is not what these servos are for. In the right application, I am sure they will be fine. Expectations need to be adjusted accordingly.The motors all worked as delivered, just be aware of differences in the behavior from one instance to another. Range of motion and precision was somewhat inconsistent. Detailed electrical, mechanical, and performance specifications would be nice to have.All connectors and wires were properly terminated and worked fine. Screws and servo horns were useful.Durability is not rated since that is a function of time and duty cycle.Overall, decent value but would not pay more. They are right at the edge of being over priced."

This is a nice set of these small servos that work well for my proof of concept project. They aren't super powerful, but not advertised as such, but they'll do the job for a project you might be planning that needs many multiple servos to work. I hooked one up to a servo controller and it worked well and was very quiet. 180 degrees of movement which will work fine for my project ahead. If you need a bunch of little plastic geared servos, this is a great assortment that will give you 10 of them. I'm very satisfied with the purchase. Just as advertised.bek

These lack a little bit and performance. But a fair value for the money. The torque seems to be adequate.Good for small light duty experimental project. I wouldn't recommend them for any rugged usegblanton

I have ordered a number of these type of servos in the past. They all look very similar with the transparent blue cases. Unfortunately, my experience has been very mixed with these cheap Chinese servos. This time, however, I can tell the product is quality just by the packaging that they used. Having learned my lesson from previous purchases, I tested all of these immediately and was very surprised that everyone of them worked perfectly with little noise and very smooth action. I hope that these will set the quality standard for all other similar servos. Very happy with this product for price and quality!What Customers Talk About
