I be travel with 2 year old twin and already have my hand full without they run in different direction . use this to attach to we luggage -lrb- both carry on and med size -rrb- and it work wonder get we to the ticket gate , past security , and even to the rental car booth . we never have to worry about where the kid be run off to - it be very easy to install and use . we kid enjoy be able to stroll through and watch what be go on around we . we receive a ton of compliment of how smart we be to get the strap and how other wish they have think of it . great product , good quality , and a life saver !
