I use them to connect pedals, but I don't own a pedalboard. They have survived dozens of concerts and hundreds of hours of practice ever since I bought them 6 months ago, but I have not toured extensively.
They are very compact because of the shape of the head and the cable. Additionally, they are rather cheap. They, however, cannot be easily soldered back if broken, and the design is such that they can be easy to break because, unless your pedal is shaped right, you have to tuck the cable, not the L-connector part. I have had no issues with hum from the cables or signal loss. Over the course of 6 months, out of the 7 that my friends and I had used, one has broken and one arrived broken.
All in all, they are very good for the price, and are especially convenient if you have a pedalboard, but don't or can't use, e.g. the Roackboard Z or N connectors.
