ok it's human nature to complain about poor service. I have 2 sqwd's on my 90 that have failed after a year of service($40-$50 for a wavemeker seems cheap) i got a new one at AZSB but I called and emailed 3iq the maker to see if i could clean/repair etc. they didn;t return my emails or calls, ok i thought no service after the sale and the warranty is 90 days. well one the guys calls and says sorry for problem. i explain i just want some input to clean and he says i am sending you 2 new ones at no charge. huh, i didn' bi*ch or act mad?. i asked can i pay the diff on one and try the 1 in. model. he says i will send that one also at no charge even though i offered to pay the difference. TRULY GREAT service.they are an inexpensive wavemaker that work well in imo and the stands behind their product . i am impressed and will buy a new one every year if they fail. WOW
