A very good quality harness. I use it because it has been recommended to me by dog trainers. I had to replace two of the original sections because my do rubs himself against walls. He damaged some of the material near the fastening, causing me to have to replace them. The material around the clips on the new sections, seems to be more robust, so hopefully it will last longer! Putting the three parts together can be confusing and particularly with the first one I bought. Once it's put together it's easy to get on and off but if someone has taken him for a walk and they unclipped differently to me, it has been confusing putting it together again. It seems to have been much easier since I had the replacement. The two news sections I bought were put together and it was easy to add the top section. The customer service is good. The staff are friendly and the order was dispatched very quickly.
