Good toy with lots of potential but also many deficiencies

The box is clean tidy with several compartments. The parts fit into each other relatively well.
The children love to build always something new. A few things have been tested so. Something bad that you have to break down the part of a complete build to the next. However, all robots can be built very quickly.
By that I mean that no part more than an hour of construction required.

Something offense is the division in it instructions. One should not necessarily start with the robot arm. The is relatively heavy and can not drive. The parts the drive can be much more interesting for children ;-)
The car for example is much better to start with. It also goes great and is fun with the separate control of the two driven axles and not sooo easy to navigate. Very quickly, it does not move, but that does not bother.

What bothers quite, but the parts are constantly break and disperse. In normal use, of course. Pull over somewhere or something to heavy lifting ...
If you drive by car normally through the area, the front wheel drops. Can be accessed using the gripper something and not let go of the time handle on the remote control, it pulls out a part and the gripper has unusable until everything fitted together again. If you move the truck a bit through the area, said goodbye to one or the other wheel ....
These are just some mistakes that make a longer playing impossible with assembled parts. We must correct every few minutes something assemble them again to expand. The gripper arm falls smoothly around on its own, if one does not increase the base body. Why is this not the same as stated in the instructions so ???
A few small Sicherungsteilchen holding the wheel on the axle and the engine, and a description of where you do not need often advise should be at the price already in it. Could save a lot of tears when the child thinks that the thing now is broken even though it has not done anything with it as normal to play !!!

The rates are the instructions:
Where exactly is the part going? How far the axis is to be inserted? Are the now 2 gears or just one?
Here, the team could safely abschauen something from Ikea. A small list of required parts in each part of the assembly drawing. 1: 1 drawings for forking and compare.
With better guidance and more appropriate images, the little machines are quite to build from 6 years together. My daughter (6) provides the exact extent to which instructions can no longer represent clearly what to do.
My son (9) and I (older ;-)) are often faced with a mystery. Hi there and can be seen only in the next steps that the part belongs just not quite pushed together because otherwise it is no longer sufficient for the motor or the wheel grinds on another part. For children's hands is the subsequent pull out and adjust the assembled part does not always provide. Of course, you can arrange, but it's not necessarily good for the motivation to continue building if a parent always has to intervene and make improvements!

The Ferndbedienung.
Quite well from her signal. 6 buttons that need not even be pressed. To go straight 2 buttons are often "push" at the same time. Because there is no depression or something that can sense the position of the touch points, you have to practice constantly look at the remote control!
Who thinks something from ???
Why not normal buttons, or at least something tactile? Hey guys, that are 6 notches in one injection mold ...

Well ...
Thus, the kit is exactly 3 star value. MMn certainly no longer.
A very good toy to stimulate learning and understanding, the child may have long pleasure. If only it were a little more thoughtful ...
It looks to me as if someone creates with not much idea in any CAD program and "tested" the processes even there. In the program it sure is going very well and the things falling apart there also not likely ...
Time to assemble yourself and test only an hour or so, smooth many vulnerabilities could reveal the need to be removed with very little effort. Instead of a wheel which is always energized, I have grown as 2 small gears. The hold much better. The tongs of the gripper arm could be further back, so that the worm does not slip, the connection so that it can not be easily pulled up to the stand space in the manual zoom because the parts are available, ...

There may be further developed and improved!

Just as the kit is now, was probably quite quickly kicked something so much money can be made.
Must make improvements not because there is smooth enough people give it 5 stars. What I can not understand my hand absolutely. At least not if you've played for half an hour with the parts.

Conclusion:
Material costs with the engines and packaging are vll 20?
Buy recommendation if the whole ~ 50 costs. For 80 too many obvious defects are present that might be at that very easily remedied.
