Not used it much! Initially it was great but now I have two flat tyres as it stopped working! It pumps air but does not grip on properly on either valve type as I have one of each and more air escapes than comes in! They are not cheap either! Give me the reliable old fashioned pumps any day!
Sound is amazing but it does keep dropping the charging so you have to re sit it and on blue tooth it looses connection randomly! It appears none of these systems work 100% for some reason? Sound is great though!
