You don't expect it to be the Watts it claims, which is true for all mixers of this type. However, since it states 45W, you expect it to be stronger than the corresponding ones that say, for example, 30W. Upon first use, it was clearly weaker compared to an Izzy Barista 30W that I have. Out of curiosity, I plugged in a power meter to see where it stands. It consumes 4.5W, while the Izzy consumes 6-6.5W. Just returning it and buying another Izzy.

Other than that, the construction is indifferent at best, generic, the same as other mixers that may claim 30 or even 25W.

For the motor it claims to have, it is quite satisfactory. I expected it to be a little more powerful in performance, but I am quite satisfied with how it works.
