I purchased the Rocket just a few days ago in hopes of creating great smoothies n protien shakes. The design n look of the rocket are pretty sleek i must say. It blends a shake in just minutes, pretty awesome. The only issue i had is one of the main points of these single serve blenders is to simply remove the cup throw on a lid and take it on the go (as i do for work in the morning), this way i can enjoy my shake as my mid day snack. However, i noticed there is minor leakage when carrying the cup when you are on the go. I had thankfully put mine in a zip lock bag just in case, which was a good call on my part. I have heard better reviews on the magic bullet, especially to just throw a lid on the cup n take it on the go without any spills. I plan to return the rocket, which is unfortunate, but oh well. Can't beat the price though if you are just looking to make shakes and drink it right away at home, or other uses that do not require to use the lid for on the go.
