Bests & Worsts Reviews from Amazon

Arrived promptly and initially functional. Dug 4 eight inch holes with plenty or torque and amazing ease. Then the clutch started to slip... more and more. Never got a 5th hole completed. Let it "cool" just in case. Didn't help. Will no longer drill even 6 inches down (in SAME SOIL as before) without just sitting there and slipping. Seller tells me (in broken english) that I "just need to drill smaller holes" that's not going to work to sink 4 x 6" posts. Then I am told "it's too late for a refund"... I never asked for a refund. I asked 1) Is the clutch adjustable 2) If not, will you replace the unit. As of this writing I am being ignored. I will happily update this review .. IF .. they resolve this.
