CHPOWER ES121 Power Screwdriver, Compact Cordless Rechargeable Power Screw Driver, Smart Gyro Motion Control, USB Charging, 16pcs Insert Bits Kit

I purchased this for my son to use in the field when he tests and flies his drones. It really goes everywhere with him. He shared that it works perfectly and is a timesaver. He did say that it doesn't have the torque for really tight screws, but it doesn't seem to be a big issue for him.

This is a premium screwdriver, And it looks and feels as such. Variable torque and Speed are something I have yet to come across on another Electric screwdriver. HOWEVER!! Whenever i use any torque settings or max out the P mode, It just dies and the only way to get it working again is to plug it in. Works fine if it's always plugged in, But I've had it for like two weeks and I'm not impressed that I already need to compromise with this. Currently running the latest firmware 1.13.

It is an excellent product of great quality. I'm installing 10,000 small fine thread screws which takes a lot of twisting with a hand screwdriver. I cannot use a typical cordless screwdriver but this motion activated screwdriver with the blade magnetized does an excellent job and saves lots of twisting. Only improvement would be a longer lasting charge.

Pulled it out of the box. Messed with how to get it to move back and forth for a few minutes. Didn't even use it on any screws. After a couple minutes it wouldn't continue to turn. It'd turn for a split second then stop. I thought the battery might be low so I charged it full. Nope. Same stuff. Checked firmware, latest. Checked configuration file, no issues. The more I play with it, the more I think the gyro was defective out of the box. I never had any sort of speed control as review videos seem to show. I just got unlucky I guess. A replacement is on the way, so I hope that's the solution.My only complaint about it is the location of the button. Why so far up the handle? Should be much closer to the screw bit, because this is a precision screwdriver. Otherwise, absolutely gorgeous.After receiving the replacement, which is definitely not defective, I'm returning this thing. It's really well made, but I realize that having the button so far up is a deal breaker for me. It's too heavy to hold WAY up there when trying to place precision screws. The button needs to be closer to the bit. Also, the gyro thing is beyond stupid. If I start with the button straight up, then turn 100 degrees, the stopping point is now closer to 30 degrees, or something like that. The stop point moves, so if you go beyond the max angle, it's hard to know where you go to stop, So if you go back to the original position, now you're unscrewing it. It's frustrating and not at all cool. I would keep this thing if it just had two buttons.Another thing, this incorrectly uses the word "torque". There are not torque settings. They are speed settings. It comes default on speed 1. If you switch to Automatic mode, then you get finite speed control with the gyro, but it's still rather unpredictable.

Compact, easy to use, comfortable in your hand. Does the job well. Great if you have any issues with your hand/wrist such as carpal tunnel syndrome.

Works good. My led screen went out after 3 days of use dont no if it is a common problem I emailed seller never heard back.

It has a surprising amount of torque and it has variable cutoff settings. At the highest setting, it will strip the heads off small screws.

After two uses on laptop screws that were hand-tightened, it sounds like one of the teeth of the internal gears has slipped or broken. Very loud no, with almost no power behind it. Gyro is now off as well and favors the right. Even when you turn it left. Too low of quality for the amount of money asked for. I'd pay $40-$60 for this specific one. The E120 i had before this one, lasted much much longer and by a different seller.
