A must have in any tech's tool box
Use this every day at work and at home and when ever I'm out and about. I work at a ford dealership and at home. Just have an issue with the battery clips breaking off so the battery doesn't stay in when using it so watch for that but an awsome tool nonetheless.

I'm a field tech in commercial food equipment & used mine for almost everything heavy. It lasted me 6 months of heavy usage until the ratchet pivot hole grind out & lost torque-the motor still ran good. I kept the box (thanks god because I like to keep my tools clean & the serial # fade away (KEEP THE BOX!!!!). Brought it to the same mane store but @ another location & they saw that it was still under warranty. I handed them the old one & they gave me a brand new one in the box. P.S. The last few digits on the serial # is the date of manufacturing & that what counts. LOVING IT!!!!!!

mmmm I want the head size smaller like before
I work as a railroad electrical technician. The purpose of a cordless ratchet is to get into tight spaces and save time. To make a 3/8's head bigger that a 1/2 inch ratchet?????? Come on?. The 3/8 size is the most used of all.

Yes but there are problems.
I use it to remove and install panels on cars and trucks. The anvil will give out make it hard go from forward to reverse, also the screw holding the head will back out so watch out. The serial number will come off so make sure to keep the receipt.

New Vs. Reconditioned

What's the difference between New and Factory-Reconditioned?

Factory-Reconditioned products have been returned to the manufacturer and are restored to like-new operating condition; they go through a rigorous testing and inspection process. Plus, they offer a significant savings vs. new.
  • Reconditioned products may have minor cosmetic blemishes or scratches that do not affect item performance.
  • Reconditioned products may not come with all of the consumables the new version comes with (bits, sanding pads/papers, cases, etc.).
  • Both come with a manufacturer warranty and are covered by our Money Back Guarantee; New is 30 days, Reconditioned is 120 days.
