This looks to be a clone of the Makita RT0701C, the difference being it has been custom made with the ER11 collet system. There is a slight premium over the price of the Makita, though well worth it to eliminate the need for 1/8" adapters that we needed on the Makita not to mention it comes with 4 collets and a two spare sets of brushes.
Wish I would have know about this before I got my Makita.
