## Customer Reviews

### ⭐⭐⭐⭐⭐ Great precision!
*by Y***. on August 10, 2019*

This is a really nice servo, very smooth and the precision is excellent. I did notice one peculiarity, however. Most analog servos will not "hold" their position when you stop the PWM signal. At least they won't resist you turning them. These servos hold their position even after the PWM signal is switched off. In order to completely prevent them from holding a position under power, you need to actually cut the power to the servo, otherwise it will continue being locked to the last position while actively resisting any manual turning and will make a very faint humming noise. So this was an interesting observation. For those who are concerned about power consumption, be aware and modify your circuits accordingly. With that in mind, it's an excellent servo

### ⭐⭐⭐⭐ Works

They just wott

### ⭐⭐⭐⭐⭐ Finally
*by J***B on June 25, 2020*

I have purchased mini servos from different vendors for my projects and have not been very satisfied until these. The first thing is to make sure the servos you purchase are digital and NOT analog. These are digital and the chatter/drift I had before is gone. Wished I had purchased these first as the rest have been a waste of money.
