The directions were on ash to understand.  I ordered 2 and have them on different levels of a deck on the lake.  The base is really good because it can be screwed down or add weight.  So far I’m impressed.  I used two cinder blocks on each umbrella and there was a wind and they stayed balanced.  Once I get good furniture in place the cinderblocks will be hidden.  It’s a good cheap solution to not permanently fix the base to the decks.
