Purchased there over 2 years now, I can not say that I use every day, but these small bottles are still often in my fridge! Green (we do not throw the packaging), economic (making his yogurt is less expensive than buying them), practical (Q spend my yogurt purchased from Al *** g * i) healthy (no BPA or phthalates), they are easy to fill and clean thanks to the small funnel and small brush supplied with. Japprécie also caps of different colors that can quickly identify different flavors of the same tour! Finally, today, I can even add sound because after careful pre-wash with the brush, they go in the dishwasher and look like new after more than 2 years of use.
