The GE was intended to accommodate the module carrier for the cutter and is so now also used. For GE one must not lose many words: Stable, easy to use and suitable for transport. The module supports a smart, versatile system will come of it, with which you can cover almost all aspects of woodworking. The last module carrier I lack only the for the PS300.
Clear recommendation if you already have been tools of Festool or buying such contemplates. Today, I would save a little longer to take one of the modules offered completely including GE and, module carriers and machine, which is in Summer considerably cheaper than the equipment and the very useful accessory to obtain individually.
