I've been using it for about a month now and I'm quite happy with it. My few criticisms are: It sometimes slips a little due to pressure (when assembling and disassembling the instrument), so it requires some attention. It would also have been nice to include a properly sized screwdriver for easy installation and adjustment.
I ordered "Abracadabra Oboe" (instruction book), which was to have come with 2 CDs. However, I received the version without CDs with instructions for downloading the tracks. I emailed Crook and Stable about this discrepancy but received no reply. I'm quite disappointed in the lack of response.
