I have bought two electric shaker bottles and drink shakes three times a day. They have been in use for a while now and have not broken. When you go to shake the electric protein shaker bottles, they don’t leak everywhere as long as they are screwed on tight enough.
I know very few things last a lifetime, but I take good care of all my vortex portable mixers, and the voltrx protein shaker bottles are very durable. But you need to keep the lid tight while mixing to avoid adding too much water and causing protein shakes to spill on your clothes, which can be very inconvenient or uncomfortable.
