I've been happy with mine. Ecowitt sells a bird spike kit that fits it very well.
The only downside is making the bucket play nice with whatever driver you're using for the main weather station. I created a service to accomplish this, which is linked in this thread. Come to think of it, I'll probably try to get Tom to take a quick look at the service, make sure I'm following the weewx best practices. He was incredibly helpful in getting my chill hours xtype to work. Make sure if you're using a service to count the bucket tips that you have a function to disconnect the pin from gpiozero. If something goes wrong and the weewx engine restarts, if your service hasn't released the pin when it exited then it will throw an error trying to reassign the pin. Took me a while to figure that one out..
