Third time writing a review, but the previous reviews never seem to appear leading me to believe McNeela is somehow curating reviews. The product had too many problems out of the box and required multiple attempts at opening and cleaning and adjusting the right side of the concertina. some reeds on the left are breathy. The bellows leak without any buttons being pressed. Too many keys stick, requiring many self-adjustments. Screws that held the hook meant to secure the leather strap required me to tighten it on my own. Once opened there was a lot of fluff from the pads and two pads that required trimming. The only options given to me were to enact the repairs myself via an old blog post; to return ( which meant I had to pay shipping both ways without anything to show for it ) or to get it repaired/ replaced ( I have no faith in McNeela Instruments' doing a good job considering the number of problems in a NEW wren 2). I Finally got the instrument somewhat playable so I would not consider sending it back for a replacement as I may end up getting another shoddy piece that may require even more work, so I am cutting my losses. If ever I choose to upgrade, I would not return, nor will I recommend McNeela.
