Yep, have the bridle and work very well on a TB mare that I have that wouldn't relax, currently working extremely well, very relaxed through her back and making a lovely shape.......... Works for me.........
I did but it only worked when I also used it on a headcollar for at least 30mins before riding. I think that is the correct procedure anyway but it certainly worled for a horse stiff through his poll.
Worked for my horse too - you need to put it on about 20-30mins before riding tho. I just have the headpiece then you can put it on the headcollar whilst getting horse ready, then swap it over to your bridle.
