Well, I can second their claim of thousands of happy customers. Actually, the figure include their first product "Smartbin" which is in market for over 5 years now. It's still available for sale and is a tad cheaper than Smartbin Air. But I'd suggest you to go for Smartbin Air if you are looking for a completely hassle-free experience. And if cost is the factor, then you can also go for Daily Dump's Khambha which is made up of clay pots.

If you don't want to buy 2 bins, you can transfer the content to a sealed bag after the bin is full. However many people order 3-4 bins too for the sake of convenience.

Do join their Facebook community for more suggestions and conversations.

Thanks a lot for your keen interest in the product.
