ECCELLENTE

I tried it after years of using my trusty blenderbottle, and it's actually really cool and overall a better product. The plastic itself feels premium and high quality, and surprisingly it actually does mix well without having to deal with the metal ball. The only downside is that this special shape is more annoying to clean with the sponge, also there is a deep crevice where the cap thread is which you can't clean with the sponge, you need to use a bottle brush once in a while. Overall, cleaning is still fast and acceptable, and the upsides make it worth it.

Fantastic product! Works as described if you follow instructions. Had a slight issue with a small leak on one of them and the customer service team was absolutely stellar. Quick responses and immediately sent out a new one for us. Top notch company! Can't thank them enough for the attention to detail, great product quality, and super fast effecient customer service.
