Just got the protein shaker electric so I don’t know about durability or anything like that. Mixing is easy but works great. The flip top on the lid is tight enough that there are no leaks at all and I think the protein shaker mixer is perfect but it takes a lot of pressure to close completely.
The first time I used the shaker cup I added about 200 ml of milk with a scoop of protein powder and it went quite well with a smooth texture. But the spout leaked a little because I didn’t tighten it, so I now know to check if the flip top is fully closed.
