Query: Lasts Only 2-3 Years

I have bought 2 Orbit traveling sprinklers in the past 5 years. The 1st one lasted barely 3 years before the internal nylon drive gear stripped from wear, causing the sprinkler to stop traveling. The 2nd one just stripped the traveling gear after only 18-20 months - and both were used about twice a week during a 6-7 month period. Probably averaged 8 hours per week usage. This time I took the gear box apart and found that 1/16th inch wear is all that's needed for the drive gear to strip. I am going to give up on this product and find another solution. You expect better quality out of a product that claims it is guaranteed for 5 years.
