cycle trailers, has any one used one?

Am looking into buying a trailer for a 3 month + cycle tour of france + spain. Current options include BoB, Koolmule, and wilderbeast. Does any one have experience with any of these trailers?

 

I used BOB for over 5,000 miles of touring. It works well and is well made. I have gone back to racks and panniers just because I find it works better for me.
