The service from D for dog has been outstanding. The lead arrived but was faulty. I emailed them and a reply was received within minutes, apologising and letting me know that a replacement would be sent, which it was, arriving in a day or 2. The new lead works perfectly. I've found that 'Explore' is not as good as the 'Ultimate' as the tape is less substantial, however the Explore seems to be the only one in this longer length. Still, very happy with product and service.
