To says this right away, this machine is extremely expensive, however, it is worth every penny. I also own a Festool Domino Joiner, but bought the Lamello Biscuit Joiner for its capability to use Lamello's other joining elements which are unique and not found anywhere else.
It requires another cutter to be used for just biscuit joining. The machine itself is made to very tight tolerances. All fences are milled from Aluminum, not bent sheet metal like cheaper models available. Dust extraction fits perfectly to a Festool Vac. The machine comes with a wooden box and the t-slot cutter that is tequired for the Clamex joining elements. Using this machine for biscuit joining with the Lamello biscuits produces very accurate joints. I have also used the Lamello Clamex wood joining elements making knock-down cabinets. Works amazingly well with a handheld Powertool. All the jobs I have used the tool for were done almost dust free. Beside the price this is an excellent tool in addition to a Domino Joiner, but as always, you get what you pay for. I highly recommend this machine.
