You're wasting your money imo. There are only two good saws, huskys and stihls. You can buy a good Stihl at an Ace hardware for under $200 and it will last forever.
I have a husky that will cut 2 cord a day and it is over 20 years old. I recently bought a smaller Stihl because that Husky will work you to death.
I have 4 chains for each saw. When they get dull I drop them off to be sharpened.
