I dont know if any of you guys have this problem. I had a car accident about 6yrs ago and my wrists bother me alot now. Using the weedeater kills my wrist and i have used just about every commercial weedeater made. I recently bought a shindiawa weedeater and all of a sudden my wrist pain is gone. It had to go in the shop because i broke something on it and i used the other weedeater and the pain was right back. So i just thought if any of you guys have that problem you might give the shindiawa a try.
