A lot of money for what it is.
I'm giving Gencon 3 stars because their customer service is good. Their website has very helpful videos explaining how to fit and use their collars and leads.
I'm deducting 2 stars because the leads are a thin strip that aren't comfy to hold (I bought the mini all in one for my Sproodle) for the price, its more than basic. So I paid £21 for it and had to buy a separate safety clip to attach to her collar incase she got loose which was just over £5. Then there is the p+p on top of it. With my 10% discount it still cost £28 and it is no better than the Halti collar! It doesn't have a different or better outcome. Not only is the Halti collar only £10, but it comes with the safety clip as standard.
I've gone back to using the Halti. It's padded on her nose and much sturdier material.
It doesn't do anything different, so don't waste your money.
