Before we talk about quality, let's mention the name. I bought 15-20 pieces for our customers to use in the field. My biggest complaint was that they are too fragile for normal use. The glass bulb breaks. I had one that didn't work at all out of the box. Finally, replacement probes cost half the price of a new probe, making the product disposable.
