I tested this product directly after receiving it.
My horse has back problems and is quite sensitive when I put the saddle on, even gently.
I also feel him tense when I get on a horse, he only relaxes after walking well.

I left the back warmer on for 3/4 of an hour before preparing it, and miracle! He didn't react for a single second when I saddled him, and his back was super relaxed at the start of the session.
It was available much quicker.

I also give him the back warmer after work and it seems to have an effect.

I recommend 3000%!!!

My horse seems to appreciate it, I give him 20 minutes before and after either a riding session or a lunge. During the pose he tends to fall asleep and/or chew and during the session I find him more available, less tense behind his back with a more active step. To see in the long term but over 15 days I am rather satisfied.

This back warmer is my essential tool before a session in winter and summer and depending on the session it has afterwards! How can I tell you that he loves it so much that he falls asleep with it!

This back warmer is truly incredible. I use it especially after a massage because my mare has become retired. I also tested it when lunging my mare. Nothing to say except that it must fit the shape of the horse as closely as possible compared to the standard carpet and on mine it's not great but I don't regret it.

I 100% recommend the product, especially if the horse has a sensitive back. The heat comes quickly, super effective before work and even on the loin, really great!
