Front no locknut or similar for fixing the buttons is available. A round ball with a thread that is very easy to loosen by itself no matter how firmly you can rotate it. I kept it anyway and after a summer it's broken. The wind tore formally the Sail Away! It also can not rotate in the wind because no joint exists.
For all who want a Windrat stainless steel, buys none of Blomus !! Although it looks classy, but processed and installed on the cheapest. Clear the price is not high but the plays for this result really does not matter anymore! The people you're trying to attract by the word "steel"! But nothing more !!
This recession refers to the 20cm and 30cm pinwheel.
