While looking around to buy another wireless thermometer for my smoker, I came across this company. They seem to have med to good reviews in the USA and have a range of wireless units, now I checked as best I could and I found out the the spec's are almost a knockoff of the Mavericks. When I looked up place of manufacture of the Mavericks it is China and same local as the Thermo Pro's.
When I searched the web you could pick up one model delivered for under $40 au, it has me half interested in giving them a try - plus they have life time warrenty on the probes.
