Quite ok, with room for improvement

The following should be noticed that bother me somewhat.
a) The wood has some protruding splinters, where you can get hurt. One should deburr the product before handing over to the kids accordingly once.
b) Since the wood is untreated, you should, in order to protect it from the elements, painted before the first use. Was me, however when ordering already aware.
c) The wheels are not secured by screws or nuts, but only by pigtails. Although the sit tight, but can be hard to lose weight. If a wheel change necessary / desirable to be, which could be a major problem / expense.
d) The Deixel is classically mounted with screw and nut. For easy transport, eg. As in a car, it would be nice if there were this a quick release, for which no tools are required.
e) The four boards of the building are only plugged in and not fixed and may be removed. In my view, according to which is a security risk. It is better if better still ran the boards by screws and nuts, secure quick-release fasteners would.

Otherwise the carts do what he should and does the job. We will paint it and continue to use.
