Equi-measure lunging aid

[Redsara]

Has anyone got experience of the equi measure lunging aid?
I have just bought one. It is intended to stimulate/encourage the use of the adominal muscles to lift the back and improve carriage.
My mare is very reluctant to use her abs (no response at all when running finger along belly or pressure points on rump!) and I was almost going to buy the equiAmi combo when I came across the equi measure. Thoughts please......

I looked but thought all my horses would be likely to freak out at it. Be interested to see someone not paid to advertise its views tho!

I have one. Haven't used it much (not for any particular reason) so can't comment really, but expected my horse to freak out and she didn't at all, apart from when it was too tight. I do think she finds the crupper bit uncomfortable which may well counteract the effect of the belly strap.

I have looked at them but decided if I needed something like that I could make it very easily .
