I have this essay then ordered together with the eccentric attachment for the Bosch IXO here at Amazon, and thus also satisfied. The material quality is solid. The attachment to the IXO is relatively easy on the hand. I better I do not say much to the intended use. Great stuff if too little space is available to screw and IXO to put a row in an axis. The angle attachment is definitely worth the money (though you probably rarely need it).
The only drawback is as with the eccentric that the packaging of the IXO unfortunately provides no storage for the essay. But that belongs more in the review of the IXO.
