This is a very well designed product by Amijivdaya. It avoids spillage of bird food due to is thoughful design and bottom plate. Birds seem to recognize this green bottle and love it, as earlier I used to keep same bird food in plastic container, but fewer birds used to eat from it. However, after putting the food in this, many sparrows and parrots and (unfortunately) pigeons come to the window and play on this hanging bottle daily (these birds were always present in my locality, so dont expect this feeder to attract birds from far away). The chirping of birds sounds soothing and impacts health positively. The only 2 complaints I have from the company are - 1. The slots/openings in bottle do not seem sturdily fit, as they turn around when bigger birds like pigoens eat from this - try to fit those plastic pieces tigher. 2. Considering that this is a very simple plastic bottle and with some plastic parts, this seems to be over-priced. It would have been ideal if this was sold for 80-100 Rs / bottle max incl taxes.
