True , but if using them for shopping they need really good brakes...always somebody stopping in front of you in the middle of the isle...not enough room to go around or someone else is coming. Then they go swerving blocking your pass, then they stop again...in the middle. Excuse me...sh*t must not know english. Can't turn around it is starting to get backed up behind me now. Only a minute left to the end of the isle...I will go a different way then.
