Its by thermoworks but isn't a thermapen. Its way cheaper than a thermapen and still does a darn good accurate job in about 4 seconds. If you only want to spend around $20 for a GOOD
thermometer then get this one. I just ordered a second one last week.
Plus, if you can't wait 4 seconds to get an accurate temp and really really REALLY NEED
the instant one for $90, then you are booking yourself to tight my friend.
