4 Pcs SG90 9G Micro Servo Motor Kit for RC Robot Arm/Hand/Walking Helicopter Airplane Car Boat Control with Cable, Mini Servos for Arduino Project

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.

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.

I used these on my first fixed-wing build, a Sky Surfer X8. The servos fit perfectly, and worked just fine on the first attempt. They have lasted at least 10 flights so far with no issues running on my 3S battery setup with an X8R Frsky receiver. Can't beat the price, plus you get some spares incase one does go bad.

Plastic gears.They work well for RC planes. Low torque situation. Very affordable. Great shipping on time

Proper packaging that protects the product during transit. All 12 were tested immediately after arriving and all 12 passed. Very satisfied with the product and the seller.

These have held up well. Only used indoors but no issues with functionality. Currently use them for model armatures with a remote. Would be good for all kinds of modeling.

I recently picked up a 10-pack of Smraza SG90 9G Micro Metal Servos for my DIY robotics projects, and my experience has been a bit mixed. On the positive side, the servos that did work delivered the expected torque and responsiveness, allowing for accurate and stable control. They integrated well with my Arduino setup and seemed to hold up under moderate loads, achieving the advertised 9 grams of force without issues.However, the biggest disappointment was that 4 out of the 10 servos were defective right out of the box. That’s a pretty high failure rate, and it’s frustrating when nearly half of the set is unusable. The functioning units are reliable and do exactly what I need, but the quality control concerns make me hesitate to recommend them without reservations.If you’re lucky and all of them work, these servos can be great little helpers in various projects. But the risk of receiving multiple defective units is something to keep in mind if you’re considering this 10-pack.

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!
