UPDATE( 06/04/2017) : for video Review with complete explanation & Demo, please check video on my the youtube channel - sameers reviewroom.I have being Using this Screw Driver for 1 YEAR now. I am a MECHANICAL ENGINEER and have used this product very Rigorously for many Projects.Following are the Pros and Cons Observed by me,--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------Pros :1) It can UNSCREW everything except the Hinges of the furniture. That can also be Done, but you need to Loose the screws initially and then use this Screwdriver.2) Has lot of Torque Adjustment. I have Used this product to Unscrew Laptop screws ( requires very Delicate Pressure) to Tightening C-Clamp ( requires High Torque).3) Best feature is NO-SLIP setting. The very Last setting( See the IMAGE for Details ) of torque Locks the Gearing Mechanism and Avoids any SLIP possible. This can be used for High torque projects.4) It has nice Locking Mechanism, which Avoids the device to Start when False Trigger is Pressed.( See the IMAGE for Details ).5) Handle Swing Mechanism is also very useful , when you Don't have Space to work in GUN position OR need Extra Pressure to apply from your side.6) Battery Light Indicator shows intensity of battery in REAL TIME. ( All 3 Lights On- Full Charged, 2 Lights On - Half Battery, Red Light On - Low Battery ).7) On Full Charge, battery lasts for 5 - 6 Hrs. of continuous Load. The battery Backup varies as Per Torque Adjustments. It takes almost 3 Hrs.for complete Charge.8) Handy LED Light, Not that useful but Serves the purpose. ( See the IMAGE for Details ).9) It is Cordless, So you can Take it Anywhere you want and use it at Any Location.10) Finally it Looks very Aesthetic.Cons :1) Feels BULKY when you need to operate for Delicate Project, rest there is No Issue.2) LED DOES NOT Lights the area properly.( See the IMAGE for Details )3) One of Bit ( CR-V2 ) slightly DISTORTED at the Top. ( See IMAGE for Details )------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------USEFUL TIPS to EXTEND LIFE & APPLICABILITY :1) DO NOT Use the screw driver on MANUAL MODE.that is by turning device OFF DO NOT SCREW or UNSCREW. If you use the device Manually IT WILL DAMAGE the GEARING MECHANISM and Ultimately complete device.2) DO NOT cover the Vents( See the IMAGE ) with any Sticky-Tape or anything.This will cause the Machine to Heat-Up and Reduce the Life.3) IF you want to Extend the Bit collection for this machine. Purchase any Multi-Purpose Screwdriver or just Extra Bits, REMEMBER to Get the Bit of Exact Same Size or Smaller Size.It will Cost you NOT MORE THAN 500 Rupees.Then use Socket Extension Adapter of Proper Size, just like One provided in Original Package. Now you have various Range of Bit Compared to ONLY 15 in Original Package.-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------VERDICT :For the Given Price, its the Best Power-CORDLESS Screw Driver you Can Get in Market. Remember to Follow the Above Precautionary Tips and You are Good to Go with the Screw Driver for Long Time.Thank You.
