Years ago when they came over and we asked them to look at our system we expected that they would try to sell us more than what we ended up needing. So I was happy about that. The only thing is they sold us a infrared light that work, it's still the same, uv light I'm sorry. It's a unit that your water goes through to take the bacteria out of it and you have to replace it once a year you have to pay for that. You have to pay for the services cause they are not going to replace it. What they didn't tell us was that there was some kind of defect with the first one they had given us before this, well actually this last time, that made it give off a sound that was really really annoying and it was nothing that we couldn't deal with and my husband has a recording studio right next to where that thing is installed. And we could here it in another room you know you know, and it was really annoying and when he called the guy who was here, the guy said yes some of them are like that, and he left. So finally after few days my husband call them back and said look this isn't right,you have to be able to do something about this. What they did was, they had already charged us to exchange the the bulb thing, we said well the ones that they said actually they fixed that in recent year or something and he never told us that there has been an alternative. He come out and charge us, we ended up paying another actually couple hundred dollars in addition to just have, they took the whole thing. Instead of doing us the right thing in the first place they charged us a services call and for a whole new unit but the original one was defective he said there was a defect in, and that what they had given us. And we sat there and we were shocked. Here is kind of the worst part, my husband call back we were really upset about what we had to pay for this thing, really the yearly payment for just changing a a uv bulb in this unit was you know would come up to like $75 or something like this and this was well over $200. And it wasn't acceptable as it was. It was crazy and when he called back and talk to the guy that runs the place the guy said well, just basically he didn't hear and he said you know I don't really have time to talk about this and I don't know what to tell you. And that really shocked us because what he said several years ago when we first had them come over and to be fair I have to say that their sales rep was someone that we knew in the family, my daughter's boyfriend at the time and now my son in law. This girl who was the sales rep was actually a singer in my sun in law's band and I thought that we needed like a water softening system because of things like, we have a well and she said no no no no this is what you need. Cause we would have the water tested and so forth and she did other tests and she said other than the bacteria she said you have excellent water and this is all you need so.
