String Trimmers

i have owned 2 troybuilt 4 cycle weedeaters that i have not been pleased with either of them. I did some checking and decided to purchase a husqvarna 224l trimmer and was tickled to death never seen a weedeater work so well. this expierence led me to buy a rancher 450 20" chainsaw and a lgt2654 riding lawn tractor. all have been fantastic products untill this year after 1 season of use i get out my 224l and it starts right up mowing down weeds like crazy then all of a sudden it quits and is very easy to turn over since i mechanic for a living and the warrenty has run out i proceeded to tear it down to find the problem. it did not take long. the piston had busted off the connecting rod. now im am worried about my other products and wonder if i should change to another company. as i said husqvarna seems to make good products and my chain saw has cut up several cords of wood since i have owened it. just wondering what husqvarnas thoughts are on my expierence with there product and if they value me as a customer
