Yes, the rain collector can gather, that works rain. Also, the building is - as long as you have a helper for the insertion of the bag - not too difficult. But nowhere is that you need a solid and level, preferably concrete or tiled room for it, otherwise the rain collector is not right. And apropos are: It is an extremely wobbly thing as long as he is not completely filled, and breaks down into its individual parts, if you are not attracting the puny turnbuckles "as an ox". The best way is to buy the same even bungees to. If I would not have put so much work in building up's, I would send him back again.
