Barely operates. I charge it fully and then go to use it and it says it’s out of battery. I have to plug it into my car usb charger just for it to work which almost defeats the purpose of it being portable. Not only that, but it stops running after 3 seconds and blinks with an error if it deems your contents too frozen. So I end up with a watery, crunchy smoothie while tethered to my car. I thought I would just deal with it but now it’s too late to return it and I’m fed up.

I add milk, preserves and soft ice cream scoops with a spoon and it won't blend that. I have followed smoothie recipe making sure to add ingredients in order and it jams up. The base only holds charge for 4 blends so keep the cable close. There is absolutely no way this will blend ice unless the ice is thawed (water). This is my first and will be last nutribullet product. The positive about the flex it does come apart nicely for cleaning.

A weak motor - hard to crush ice cubes with yogurt and milk. Needs to be recharged often and needs full charge to have the weak motor

good concept - but not stable. motor stops when blending as it comes loose from base

This was given as a Christmas gift. I was super excited to use it and boy was it a let down. I’m appreciative of the gifts it’s not the gifters fault the product was awful. We’ve given this so many chances and every single time it lets us down. It gets stuck on protein powder, got stuck on bananas this morning, god forbid we make it try to blend ice; it couldn’t even blend up a frozen blackberry. These 5 star reviews must be bought and paid for; you can even see who received it free and was incentivized to review. Do not waste your money on this crap, I’m glad I didn’t. We’re going to have to spend money on something way better. At least this was a good baseline to use as to what specifications and brand to avoid getting on our next blender. Please do not buy this. You will be disappointed
