Kind of Complicated for a Hood

I have not had any issues with contamination with this hood which is great and I love that the UV light turns off automatically after 30 minutes. However, the glass has to be in a very, very specific position for the alarm to not go off. In order to combat this issue, I put a bit of tape down to help with alignment. If it is off by a centimeter, it will alarm. It is very annoying and it took me more time than I would care to admit to address this issue. They should have installed a sticker like I have put on or a latch to show exactly where this glass needs to sit. This is a great hood but the ergonomics of this product needs some serious work.
