Anyone using the Dually over the kemp controller is mad!!
The kemp controller costs a fraction of the dually does and it comes in one size to fit all. the dually is very pricey at £30+ and in pony, cob, and full and the Kemp controller is £8.00. I know which one I would have. It works...
Nay use a kemp controller. It works brilliantly, Its simply and basic design seems like it wont be strong enough but believe me it is. You can buy them so cheap on the products' website. I keep it on my headcollar at all times just in case thats the beauty but do not tie the horse up with it...
