I went here to have my kegerator co2 tank filled. They all were out on calls so the gal at I spoke…read moreto (who was super friendly) told me to I could leave it and they would call when it was ready. They called about an hour later and I picked it up. First off, the staff (and I think maybe the owner) we're all very friendly. They inquired if this was my first kegerator and I said yes. They then took time to go over some kegerator hook up situations and how to avoid them. They absolutely go above and beyond and it's obvious they care about their customers. Filling a tank was a small job both monetary and work but they treated me as if it was any large purchase. The rates for filling are absolutely unbelievably reasonable. They obviously do fire protection sales and repairs it appears, but treat even the smallest requests the same. Love the customer service.

I have had the worst experience with ADT. I've been a customer since 2001 and had great service…read moreuntil I tried to cancel the CCTVs since I'm not using them anymore. This is on the new property that I have been at for 7+ years. I have called 7 times thus far with a minimum time online of 50 minutes and I end up talking to several people one after the other. They cancelled my account altogether and now they are back-charging my account when they were not protecting my house!!!! This is disgraceful. Today, I've talked to 2 different people in now 40 minutes and no one can tell me if my house is indeed monitored again and why I see a $400 bill suddenly show up on my account. I have yet to get an answer after calling 7 times!!!!! What type of business has this become?!

I've had a very good experience CPI so far. It's certainly better than ADT. I had them in one house…read moreand then they moved the system to my new house. The customer service is great and so are their technicians. In response to the one-star reviews--of course there's a contract. They spend a lot of money setting the system up in your house and it will cost them a lot to have it removed if you change your mind. Any company that installs and monitors a security system will have a three-year contract. Otherwise, they wouldn't stay in business. The three-year contract was explained to me over the phone and clearly stated in the contract that I signed.
