After building the Hedwig, also produced by a no-name company, I thought it's going to be OK while building Wall-E.
The set itself is great, building the robot was fun and there are fairly interesting techniques in use.
The problem lies within the instructions and the quality of bricks.
Instructions are grayed out for the steps you have already completed (instead of highlighting new bits on the already completed, coloured structure), so sometimes it takes a while to determine where are you bilding next and whether you have missed something. Another thing is that the stepd are sometimes not in the right order.
When it comes to bricks, it's modtly acceptable in terms of "classic" bricks, but the Technic parts are way off in terms of quality. Parts are sliding in or out whether you like it or not, and sometimes you will struggle to connect two parts together.
My set had one brick with different colour than it should have, so I spent a lot of time looking for something that wasn't there. Another brick was melted and unusable. Wall-E's tracks are of such bad quality they barely spin.
Overall I'm disappointed with the quality.

Lot of fun for low payment

It's a fun, easy and cute build which every collector should have. I had only one small piece missing but replaced it with one from another set.

Great set with the motor and very good service

Nice build. But the neck is a bit instable. The original Lego set got a change on this problem that was not included in this set unfotunately.
