When out and about with my kids it gives me a sense of security to know that I can lock up my buggy/stroller with this lock, it's strong and safe and has a foam around it which stops it from scratching the buggy.
It is a dead simple combination lock that is very fast to apply. I slip it over the main handle bar of my Mothercare Mychoice (it matches the handle wonderfully) or around the frame of my Maclaren. When I have to leave my buggy for even a few moments, I can find somewhere to hook the clip onto, snap it shut and turn the combination. Easy. I've used it on park railings and outside supermarkets but I recently saw someone in a cafe attach their My Buggy Buddy lock to a spare chair while they popped to the baby change – if someone really wanted to steal their Buggaboo then they would have had to take the chair with them!
