I have a lot of arthritis in my hands but like to build stuff and tinker. This driver works well. Controls are brain dead simple, and the motor has lots of torque. I've been able to reduce manual screwdriver (actually Allen key) use on a large kit project to maybe 25% of the screw tightening (mostly setting the screw and final tightening on more delicate parts.) My joints love you, Fanttik! I particularly like the variable speed, unlike other similarly priced units. Power: I was able to drive about 50 short (~10mm) 3mm bolts and still had 3 bars of power out of 4. Shape of the driver is ergonomic.A word of warning for new users: there's very little tactile feedback like there is when using a manual screwdriver, and you don't feel the resistance to further torquing in the same way. I did manage to strip a screw and a nut before I got the hang of it. Use the variable speed, go slow, listen to the sound of the motor, start at the lowest torque setting, and stop driving as soon as there is the least bit of resistance (typically sensed by the tool starting to turn in your hand.)Definitely, definitely recommend.

1. USB-C Compatibility: The Fanttik screwdriver's USB-C charging port offers exceptional versatility, allowing it to be powered by all charging devices!, from laptops or laptop's chargers to any wall chargers. For example, I was able to use my 120-watt USB-C laptop charger to quickly recharge the screwdriver, consuming only ~10 watts of the 120 watts available power.2. Adjustable Speed: The push-button (trigger) controls provide precise speed adjustments. Eg. the convenient speed adjustment allows easy to start any bolt screwing down, sometimes even with partially damaged threat.3. Ergonomic Aesthetic Design: The comfortable grip and well-balanced design ensure a pleasant user experience.Cons:1. No Charging While Using: Unfortunately, the screwdriver cannot be used while charging, which can be frustrating for extended projects. For instance, during a kitchen cabinet assembly, I was unable to continue working after connecting the screwdriver to my 100% charged power bank.2. Weak (for even a few hours intense work) and leaky battery. The 100% charged battery lost 25% after 2 weeks of resting inside original plastic box with normal room temperature and humidity. The battery's longevity may be an issue.Overall:While the Fanttik Cordless Screwdriver offers versatility and convenience thanks to its USB-C and USB-A compatibility, its inability to charge while in use and potential battery weakness may limit its practicality for some users DIY-rs, especially those requiring extended work hours.Suggestions to beat competition.To enhance the Fanttik Cordless Screwdriver and gain a competitive edge, consider the following improvements:1. Replaceable Battery: Adopting a standard 18650 battery format, similar to the Coast XPH30R Headlamp, would provide users with more flexibility and the ability to easily replace the battery when needed. Additionally, using USB-C replaceable battery would align with the current industry standard and offer greater usage. Coast Company uses 18650 WITH USB-C !2. Power-Saving Features: Implementing a simple switch to turn off powerful LEDs during daylight use could significantly conserve battery energy. For more advanced power management, incorporating a photo-censor switch that automatically adjusts the LED brightness based on ambient light conditions could further optimize battery life.By addressing these design considerations, the Fanttik Cordless Screwdriver could become a more attractive and practical option for users seeking a reliable and efficient power tool.

WOW. I was delighted with the quality of this screwdriver. Used this on a two-day job to build out eight small AV racks. Powered screwdriver allows one to screw tightly threaded screws into rack without stripping screws or screw holes. Worked six hours without recharging (didn't constantly use screwdriver) and it quickly recharged via included USB-C cable. Six torque settings, trigger allows for variable speed. Much better than using a regular battery powered drill: lighter weight-easier to grasp (less wrist fatique), chuck locks bits into place. Only disappointment is that the hinges on the plastic case are weak and split apart after only one use.
