Review on KIMO 20V Cordless Impact Wrench Kit - 1/2" High Torque, 3000 In-Lbs & RPM, Battery Driver With Fast Charger LED Light 7 Sockets by Gervan Mauldin

I primarily wanted a 1/2" impact as a backup so I could leave one in the car for quick tire changes. My 10 year old Craftsman is still working fine, but is being used more in the garage for both automotive and home projects. Out of the box I was happy to see that the KIMO purchase included various socket wrenches (one less headache to deal with as I have sockets for the Craftsman in the garage and I did not want to risk losing any of them by switching between two impact wrenches. Well today I wanted to replace the pads and rotors on our '17 mazda 3. I set the torque on the lug nuts of this vehicle specifically at 94 foot pounds. Manual says 80-108 foot pounds so I always average the range. With a fully charged battery and fresh out of the box the KIMO could not budge any of the lug nuts. I thought.well that is strange. So I went ahead and loosened all the lug nuts and re-installed them with a torque wrench again at a somewhat lower figure of 90 foot pounds. Retried the KIMO.pap.pap.pap.nope.it was not able to even budge any of the lug nuts. I went ahead and placed the KIMO battery back on the charger. It was fully green after about 30 minutes, but purposely left it in the charger for 3 hours to make sure. I went ahead and replaced the pads/rotors on our Mazda with aid from the Craftsman impact wrench. Just as a test I purposely put the lug nuts at 80 and at 70 foot pounds at the front driver's tire (3 at 70 and 2 and 80). I brought out the KIMO and attempted to loosen the 2 lug nuts that were torqued at 80.NOPE.not even close. I went ahead and tried the 3 that were set at 70 foot pounds.NOPE.did not even budge one of them.I am not sure what to make of this. If the KIMO cannot even budge a lug nut at 70 ft/pounds what is the point of having an impact wrench to remove lug nuts? I even went across the street to our neighbor that has a M5 (he was putting the stock rims back on with road course tires). He removed his passenger rear in about 30 seconds with his unknown impact wrench (probably a yellow/black dewalt) and I could not even remove the first lug nut on the rear driver's side. He said he put the lugs on his wheels at about 90 foot pounds.also mentioned he never heard of KIMO and that is probably where the issue is.you get what you pay for even if you are just going to use if specifically for lug nuts. I really wanted to give a good review on this simply because the main purpose was to remove lug nuts (nothing crazy like major suspension pieces that require 120 foot pounds bolts.). It just did not perform as advertised and hence my low rating.
