Initially, I ordered water service from Sparkletts after having seen their water cooler in an office I was visiting, not really knowing much about Culligan at the time. The experience with Sparkletts was absolutely horrible to say the least. My initial set-up and delivery kept being rescheduled without my knowledge and after several rounds of that, I halted, cancelled, ceased, discontinued and stopped any and all forms of business dealings with them. I knew I needed another option and didn't necessarily want to use Ozarka. I saw Culligan on the internet and decided to give their service a try. The difference from the very beginning is not even comparable. I submitted my inquiry, and the same day I got a call AND delivery even though it was near the end of the day. Our delivery guy Mitch is always right on time, very pleasant, and goes out of his way to make sure we are taken care of. I recommend Culligan to anyone I can think of. I even told the office who uses Sparkletts to give them the boot and go with Culligan. Not sure if they did, but it's their loss if they didn't.
