I'm a fan too, I first saw one on Ann's little Marcel, and he looked so cute in it, I guess I loved the leather and the stainless steel together, reminds me of Marlon Brando’s motorcycle jacket!
I've had one for Joey for about 5 years and it's gotten better with age, and just got another one for my little foster, who has had trachea problems and this doesn't come close to his throat, so one less worry! My last one came from Muttropolis and they have great service and you can google discounts.
