This is a hefty portable blender! It weighs about 2lbs without any ingredients inside. After blending though, the weight can be lessened by switching out the lids, keep in mind that the to go lid is not leak proof so the cup need to stay upright. It says that it will keep cold for 24 hours but haven’t tested that yet… I  can say that after an hour the smoothie I made was still nice and cold.  The instructions are pretty straightforward, but I’m still trying to figure out how to NOT get any powder stuck in the lid opening. I have had to run it twice a few times but that’s ok for the convenience of having it. Also, it isn’t very loud. Easy to clean. So far nothing has stuck to the motor base blade lid. Tiny bit of learning curve, just make sure you go through the manual first, it’ll make that first blend go by smoother :).
