I have two of the blenders in the online store at home. It's the one called "great and powerful blender" and "stylish and practical blender". Both are good in their own way. Here are my pros and cons of these two and other travel blender tips.
Great and powerful blender:
Advantages: Solid glass, dishwasher safe, nice size, easy to take with you on the go, fits nicely in your backpack, has a good lid with a good "drinking spout", can be recharged
Cons: A little big in the bag, a little more expensive than the other one
Stylish and practical blender:
Advantages: Small and light and easy to take on trips, fits in both a small bag and a backpack, can be recharged, comes with two drinking glasses, cheapest
Cons: Made of plastic, not dishwasher safe, needs to blend in two batches to fill both glasses, needs to be charged more often than the other
These are my thoughts on these two, but as I said, they are both nice in their own way and you have to decide this for yourself based on your needs.
Otherwise, there are several other nice and good blenders in the shop and you can find them here:
