Wireless temp sensor replacement

Great sensor, easy to install and connect with my weather station (less than a minute)

Great Service

Ordered and delivered on time

Poor Quality

Gave 2 stars for fast shipping. Poor quality. Stabbed around 10 bales and it’s already bent. My bales are tight, which they should be. Why would you make a probe with a blunt end and not pointed? This probe is so difficult to get into my bales and due to this, the head is already bent.

I really like the product.

Good features, needs gentle handling

I'm buying a replacement because I use it in my truck and it works well. Because there's no metal to attach the magnet to, I lay it in the little coin compartment above my left knee. I pick it up to read it, so the wire gets flexed a lot where it enters the housing. The insulation wore off and the wire shorted out, so I get a reading of HH.H for the outside temps. I'll probably reinforce the wire on the new one with tape or silicone caulk.
