I didn't use their service, so no feedback on that. Here's what I experienced (and I'm THANKFUL for…read moreon-line reviews and comments). I met these folks at the recent Home Show in Overland Park. Even though I think our water quality is great, I signed up for an analysis and a free water filter. After the show, I received multiple calls to schedule this, and finally decided to answer the call. Here are the two things that got my spidey senses tingling. First of all, nearly every reference to confirming the appointment included stating that 'my spouse/partner' was to be available as well. That immediately gets me to thinking this is going to be a high-pressured sales call, something I don't care for. In fact, that's what reviews confirmed for me - once they got into the house, it could be hours before they finally got the message. Lastly, once everything was confirmed for the appointment, he then said he was going to have me chat with one of his managers. When she came on and verified the info, including the spouse/partner thing, I could feel the regret starting. When I hung up, I did my review online. Service seems to be rated very highly, which is great. What I didn't want or need was a relentless, high-pressured push for something that may be marginally helpful but probably not all that necessary in Overland Park.
