  • What a great tool! It drove lag bolts and all different length deck screws with no loss of power.
  • This is the best cordless impact driver on the market! I have tried all the other major brands and I still like my Hitachi the best.
  • I give the Hitachi 5 stars for fit and finish with solid construction and a rubberized outer cover to absorb shocks and bumps. The collet type chuck is easy to operate and the small size and light weight of this thing are truly amazing!
  • This is just fantastic. Hitachi hit a homer with this impact driver. I've driven 4" screws into oak with this thing with no effort and was just amazed.
  • Impressed so far and I give it 5 stars for build quality, value, performance, and general coolness
  • One of the best tools I have ever owned. By far the best drill ever made. The power is unreal, and it weighs nothing. I am a General Contractor and have been in the building industry for 23 years
  • I have used the tool several times and am impressed with the power and weight of the tool. I would have given the tool 5 stars but the green and black design looks a little Fisher Price to me.
  • What a powerhouse! This will drive a 5/16" lag screw into 1 1/4" decking with no torque on my wrist! Will save me much time and fatigue.
  • I've been using it for over a year now...The battery life is outstanding. They hold their charges well between uses, and have survived banging around the back of my van for a while now.
  • This little machine is incredible. It is my most used power tool. I am a remodeler, I wasn't sure if I should believe the hype about impact drivers, but I gave it a try anyways. I have never looked back.
  • Worth the money... I've used my cordless impact every day at work for the past two months. It's lighter than my previous Hitatchi 14.4, and has way more power..highly recommended
  • This impact driver is stronger than almost all other brands, and actually is not as loud as most other brands.
  • This is a great product from Hitatchi...strong driver for long screws into wood, compact size and weight, long battery life, cool alien pattern on handle, good quality case, ease of use
