i have since found out that all rental agencies do not require you to buy the full package- i was not given that option. unlike spit, urine or stool, it would not be over even if you clean or take bath. the bee is unaware of it’s higher purpose but you don’t have to be. this top was only £8 which is a bargain. the equipment is no longer functional and cannot be repaired or it is not cost effective to repair.
