I've had a Polder for about 10 years. I've had 2 Pyrex for about 5 years over that period I've replaced 2 probes. Other that that they've all worked just fine. I also have a Maverick ET-72 and although it's very convenient when it works, the unit is very unreliable. The remote unit keeps losing it's signal and I have to go outside to reset it. That inconvenience makes it no more convenient than the standard Polder, Pyrex or Taylor. I've talked to Maverick about the problem and they tell me that it's being knocked off line by other devices operating on the same frequency. That's good to know but of little help. Bottom line, the thing is still unreliable.
One other thermo you might want to check out is the Thermapan. Very fast read and real accurate. Great for when you want to make that final temp check in several different locations and not keep the door open for too long. The only drawback is that they are kind of expensive. Here's a link to the
Thermapen web page.
