We play with this set – Georello Gear Tech by Quercetti – for a long time now, making everything turn. You can also add cardboard pieces to it.
These gears by Quercetti has all the essential thing you’d desire in a gear system. Firstly, their construction quality is top-notch, and the pieces have robust and solid design. The set also has a seamless gear interface, so they interlock securely. With this reliable connections and sturdy pieces, the set allows you to build machines that can perform real work.
The set includes several base plates that fit together like puzzle pieces. Nearly half the time these are in use at our house, kids made colorful boxes from them. So, they’re not just basic pieces but are interesting decorations in their own. The second set of pieces has support structures, which are tubes and joints that interlock to create sturdy poles. These pieces come in a consistent size, without the frustration of dealing with components at slightly different heights, a problem we’ve encountered with other sets in the past. The support connects are sturdy, so that the structures stay intact once they’re built.
In addition to the gears, this set also comes with attachments like chains and rubber bands. You can use them to connect groups of gears that would otherwise be separate. Also, you can use them with other toys and building sets.
