    Overall, my experience was excellent and although the price tag was much much higher than I expected to spend it was well worth the money. This is one case where I have to say you get what you pay for in terms of professionalism, organization, superior product and most important for us, your warranty. We are preparing our house for sale and the wet basement was a huge issue and now it is perfectly dry and completely a non-issue as we can point to your product and your warranty.
