Did a lot of research and the Mastershield product seemed best, I had a few other brands give quotes as well ***** etc. and while not the cheapest the MS product itself along with the lifetime warranty was best. Jim who did the initial run through and quote was professional and picked up on things that others did not notice with the current gutters. The office even send 2 diff sets of color MS covers to make sure the color was perfect. Install was smooth and professional as well, new gutters and MS installed in a day. So far so good, and with all the rain we have had thus far in Seattle the products and install seem GREAT.
