Review: Pricey but very good cable - Great cable for wiring up your nest, echobee, etc. Stiff and somewhat difficult to pull but great once it's done. Better than using cat6.

### ⭐⭐⭐⭐⭐ Review
*by K***H on 27 December 2025*

Good quality thermostat wire. I upgraded my thermostat from a 'dumb' thermostat to a wifi programmable one, and needed a power wire (the 5th wire). I was able to pull the new wire in the wall by hooking the new wire to the old wire and pulling it up through the wall. It made replacing the wire very easy.
