Easy to use, strong and very visible!
I hadn't used a flexi lead before, but a lot of our walks are near sheep and I have to keep my dog on a lead. I bought the neon one so that other people can see from a distance that he is on the lead (he is a big grey dog and some people are scared of him). I found it very easy to get to grips with, and the dog seems to like it as he's got more freedom to sniff! The 5m length is ideal, the lead doesn't get tangled, and the handle is comfortable and not too heavy for me.
