He took to them staight away, result was immediate, he can still eat and drink, take about 3 to 4 mins to fit, they dont ladder, knot legs at crotch and cut off legs, I make a hole with scissors and gently rip to size, tie on noseband and under chin with cut off legs trim off, remove reins and slot over Dring on bit refit reins, cut off knot so he can eat and drink, cost me £1.50 for box of five, I use one pair ride.
