Sg90 9g Micro Servo Motor, Miuzei Mini Small Servos Motor Kit Metal Gear for Arduino RC Car Airplane Robot (10)

Working fine

These work great in my 3D printed brackets that operate the turnouts on the model railroad.

12/20/18 - My SG90 ReviewI recently bought 10 SG90 9G Servo Motors from Miuzei. Best quality for its price! (Less than $2 a Servo) These servos are capable for what I need them to do mostly for small scale robotic projects. Keep in mind, some servos may or may not have the potential to reach the full 180 degrees. For what its worth, I would buy products again from Miuzei both because of their high quality product for its price range and because of their customer satisfaction ratings!12/27/18 - Comparing a MG 996R to the SG90Note: I did request a Miuzei Representative to send me a MG996 if that was possible to test. And they did!===MG 996R===Noise Level: Can be loud. Usually I hear a buzzing noise when operating this metal servo.Torque: High torque. Can be placed in RC toys and robotics. Reliable for simple and complex actions.Servo Material: MetalType: DigitalComments: From the material and torque, this servo has a high chance to survive a couple bad crashes beforebeing replaced. I have not tried this yet and will update my review accordingly, just from observation from now.from observation.Benefits: Large in weight and size. Reliable and powerful torque within its limits.===SG 90===Noise Level: Quiet, but can hear a little hum sometimes.Torque: Meant for small scale applications and projects. Reliable for simple Actions.Servo Material: PlasticType: DigitalComments: From the material and torque, this servo has a high chance of NOT surviving a head on crash. I have not tried this yet and will update my review accordingly, just from observation for now.Benefits: Small in weight and size. Reliable torque within its limits.===Comparison===Prices: Definitely worth the price for the SG90 and MG 996R depending on your applications and needs sold by Miuzei. Miuzei sells the SG90 for just about $2 per Plastic, Micro Torque Servo in a pack of 10. Miuzei sells the SG 996R for just about $4~$5 per Metal, High Torque Servo in a pack of 10.Craftsmenship: The outside design of both the MG 996R and SG90 is the same as the pictures above. Sleek, smooth, and durable from the touch. The rotation is not quite 180 degrees for each servo, so be aware of that. Will need to open the insides and see how the soldering and gears are placed. I will update this accordingly.Customer Service:The representitaves at Miuzei really care about your experience as a customer. The reason I chose to go with Miuzei out of all the other ones was their customer satisfaction and reputation in replacing servos that do not work properly out of the box (Be sure to contact them as soon as possible).My experience so far 12/27/18:I recieved the SG90 10PC Kit and MG 996R 10PC Kit within 3-5 buisness days when I placed my order with Miuzei.I am an electrical engineering student planning to tinker with robotics and design circuits.So far I am very impressed by the quality of each servo for the price I bought them at. I am satisfied with thepurchase. I would do business with them again when I need servos and I would recommend servos made by Miuzei to my colleagues as well.

I do not have much experience with servos, but these servos work fine. They are not the strongest sg90 servos, but they get the job done. I really like how screws are included with these servos to screw down the included servo arm.

After some issues with USPS, I finally got my servos in the mail. As the picture shown, the servo comes with three arms and attachment screws. One thing I would like to see is a very basic wiring diagram. Intuitively I got the wiring right but verified it with customer support. However it would be nice for beginners.Using the sweep example program in Arduino I wanted to test the five servos. All were tested and all worked. Note: the description states it will travel 120 degrees but the sweep program moves the arm 180 degrees but the arm only moves to about 170. They are advertised to be used for RC cars, planes, and drones and with plastic gears, are great for that use.Let’s see how they work under stress. I put five quarters (about 1oz.) in a bag and hung it from the larger arm off the servo. I ran the sweep program for 24 hours and it work just fine. I upped the weight to 15 quarters (3oz) and ran it for 24 hours. No issues.I wanted to see where it fail. I put 8 oz. (½ pound) on it and it swept the 170 degrees. At 12 oz. (3/4 pound) it swept at about 120 degrees. At 16 oz. (1 pound) it swept the 170 degrees but it was struggling.Overall, these are great little servos that should meet most of your needs. They work great for the money. There are higher torque servos out there but for RC use, you can’t go wrong with these.

I installed these in little 3d printed robots I built for my nieces and nephews. They do a good job and the little plastic attachment wings for the servos are better than other brands I’ve tried because they lie flat and don’t have an extra lip on both sides of the servo connection point.

Found 3 servos with the signal cable crushed and not working at all

The media could not be loaded. These servos a quite a good deal for the price. They are built similar to other cheap 9 gram servos, and as such are a bit fragile. Just something to keep in mind. They work great for small RC planes.Sadly, I found that one did not work out of the box. it made a clicking noise when first running it, then locked up. The servo gets very hot when plugging it in now. The included video shows the dysfunctional servo and a working servo. Disappointed that only 9 out of 10 worked.Update: Miuzei has sent me a new package to replace the defective servo. I apreciate that they have quick and helpful customer support and are happy to fix issues that occur!
