What is the most embarrassing photographic equipment you have ever bought?

The most embarrassing photographic equipment is the old portable tripod.

The public psychology is that buying photographic equipment will be fully armed, but in fact, some equipment utilization rate is extremely low, such as tripods.

When I first came into contact with SLR, I bought a set of tripods, that is, ordinary tripods and portable tripods, but later I found that portable tripods were too restrictive and basically useless; Portable tripod has high requirements for shooting platform. You can't use them in uneven places, too high or too low. It's no use buying it once.
