I have that unit. Dont know if it is Masterforge brand or not seeing as i got it at walmart, but it is the same unit. Picked it up for about $15. It is my thermo i take while camping just so i dont have to worry about it. Works ok, and you can set custom temp alarms with it but i have to look up how to do it every time because it isnt labeled and i dont use this unit that often. Range is ok but if i get any further than about 50 feet it is spotty. For $15 bucks though, i cant complain about it at all
