This stand is excellent to let your double bass rest. Excellent stability, overall good quality, very easy to mount.
Pros : stability, quality, reliability, ease of use... and one of the best feature is you DON'T need to unscrew or dismount the endpin of the double bass ; you can adjust the stand so that your double bass fits in it with the endpin out. Very useful for people like me who don't want nor to lose their endpin adjustment, neither wasting the pin as you screw/unscrew it every day.
Cons : can't find any
The price is pretty high but in my opinion it's good value for your money anyway. I wouldn't buy a cheaper one ; I think that about 100 ¤ to ensure your (extremely expensive) instrument won't fall down is pretty fair.
