Bought this mill to be able to cut the top and bottom side of 8-10" diameter logs for building a cabin, and for the most part it worked fantastic for that. I bought one extnetion, but wish I'd of bought 2 to cut longer logs, but the process of leveling the deck was quite a chore. I did however have a problem with the performance of the engine at our high elevation of almost 8000 feet. Customer service was extremely friendly, but provided no answer to the problem other than "get a small engine tech to look at it". They said they've never had one of their sawmills at that high of elevation before. I also had a huge challenge with shipping of the mill. Half of the package got lost in transit somewhere and I had to spend the next 4-5 weeks on the phone back and forth before finally getting all the components. Other than that, I'm super happy with it for what I'm doing.
