I just wanted to let you all know of my experience with Phillip, his product, and his competition. I moved from Atlanta, GA to Minneapolis, MN last spring and I quickly learned that engine pre-heat is a must have. I installed a Tanis system and built a ceramic heater to heat the cabin. I initially had it all tied into a programmable timer. But living 15 miles away from my hanger made it an inconvenient hassle to run out and program the timer costing me time and gas money. The decision was made to purchase a cellular activated switch.
My mistake was not coming here, to Mooneyspace, for recommendations on products first. There really is only two products that I am aware of. SwitchBox and Cell switch. I saw an ad in Aero magazine for Cell Switch and liked the price. I ordered it and it was delivered in about a week. I opened the box. Inside was the unit itself and a CD. But no paper instructions. I inserted the CD into my MacBook Pro and nothing happened. I opened the file and it wouldn't read the software. It was only compatible with Windows. Ouch. So I called Aero and asked where the customer support number was. They didn't know but they called me back with the owner of Cell Switch's number. I called that number several times and never received any support. Back in the box it went and back to Aero for a full refund.
So I ordered the SwitchBox from Phillip. It came in about 4 days. When it came I had a couple of small glitches and emailed Phillip. He responded immediately and offered to talk on the phone to help. This was on Christmas Eve!
The SwitchBox works exactly as advertised. Even comes with a pre-paid $10 T-Mobile sim card. It has an iPhone app. It is Mac friendly I guess.
I give the SwitchBox an A+. Phillip too.
Happy New Year!
