    Fun mixer truck with unexpected problems
    | 35-44
    Purchased for: Son
    My five-year-old is crazy about mixer truck and he really loves this toy. It’s not very hard to build. He built it mostly by himself and it worked! The mixer truck can function perfectly. But after he played it for an hour or so, the mixer truck now can not move forward. It can only move backwards. The drum works ok. So I think the issue comes from the back wheel. I guess he ran the truck too quickly and then something got wrong. Now the question is do we have to rebuild it from the scratch? The wheel powering part is among the first 25% of the progress. This is very frustrating. He kept asking me to buy a new one:-(

    That's no fun, a truck that won't move forwards! It does sound like something might be wrong with the build, so the best thing to do is to take that section apart and build it again. Pay close attention to the instructions, as even a small mistake can cause the model to not function properly. If you're sure everything was built correctly and you're still having trouble, or you notice any parts don't seem to be functioning properly, get in touch via and our experts will help you out.

    I would recommend this to a friend!

    Although a little tricky to build at a few points, the end result is fantastic! Very cool that you can choose to have the drum turn automatically with the wheels or with the hand crank (or not at all - thanks for the neutral option as well). Steering mechanism very similar to the Mobile Crane, nice and smooth. The pistons moving with the wheels is a fun little touch (although you wouldn't normally want the pistons in the passenger cab, at least this way you get to see them moving). I'm not a fan of lots of stickers, but was able to get these on okay (long thin ones create the most difficulty). My only quibble is that there should a brake (maybe include chocks?), since the truck moves a bit when you use the hand crank unless you hold it. Highly recommended!
