I like the controls and they work great. But the design is bad. I won't be returning them but I will have to mix up some epoxy and glue the magnets back into place so they stick to the bases. They currently cost $8.50. If you use or have some epoxy in stock, $8.50 is probably a fair price. The included batteries will likely need to be replaced with decent ones anyway, so let's call this a flush. Again, the price is fair, they look pretty decent, are small and easy to store.
