Great Price and very well made!

Great Price and very well made! perfect fit, and it looks like the same quality as the much more expensive one at the local home depot. It was easy to use and very fast and easy to change the extensions. I made several holes and there was 0 wear on them so I'm pretty sure they will last forever

Worth the money

The product is well made I am a mechanical inspector I have been one for for the last 44 years works well and did a great job.

Perfect for my electric posthole digger

Everything fits together and works well

Excellent addition to my auger!

Hi, if you need to make post holes or anything like that, even some simple excavation you should get one of these. This auger is excellent because, for me, it doesn't use gasoline and oil or has to be constantly adjusted in anyway. You just plug it in and dig. This is one of my top tools and it was worth every penny, Thank you!
