Now I have installed the collector for almost 3 months and wondered why my ton after Fertile rain so far was never full. Have finally with watering "Rain played" and found that under optimal conditions more than 25% of the rain in the bin run ("rain" is not too strong, sieve previously cleaned). If you do not constantly cleans the screen, come to about 10 to 15% of the rain. But I do not need a rain collector.
For advertised 5-minute installation: Although the installation is relatively simple, but in 5 minutes it is certainly not feasible. Even the "interpretation" of the instruction takes more time to complete.
I would recommend this product would not recommend anyone, and it will expand again.
