Nice looking duster!! Hey! I tried several times in the sand bed and it didn't work for me. I then found a little crevice for it. It seems to have to grown into that rock now and is happy!!
I hear dusters are a bit difficult to keep though. I wish you luck! Wish me luck! lol.
Had my duster for 4 months.
Hope this helps!
