Input:
I have two Polder thermometers. In the process of a remodel I placed four temperature probes (two from other devices) in a box. When the work was complete I attempted to link the probes with the proper timer/thermometer devices. Not easily done!!!  Polder, it turns out, has a different probe connector for each of its models. Unfortunately, the thermometer/timers do not identify themselves as to which model it is. The directions do identify the model but there is no picture and the probes have no indication as to which model they belong to. Couple that with the worst navigation in modern internet information, the lack of information available on some models that are still available (new), and you are left with no help for putting the right items together, no way to identify the matching item if they could be identified. No model numbers on the items and the customer service at Polder tells you they will send out information and then do not. They certainly will send a probe to you for $10+ (on a $20 item), but not tell you how to identify which thermometer the probe fits. (You won't know anyway as the thermometer or the probe doesn't have a model number on it.) Seriously, how difficult would it be to color code the probe with the thermometer receptacle, identify both the probe and the thermometer with a model number, post directions and a guide to matching items? This is Marketing 101.  The thermometers work fine but only if you put the correct probe in the correct thermometer. (Why six different probes that don't work in any but the matching thermometer--which is not identified by a picture or a model number). Polder hasn't a clue when it comes to the customer. Bad, bad, marketing.  If you have only one thermometer/timer and one probe you're probably OK, but if something goes awry you're screwed.  Polder doesn't get it.
