If you paint in sand forget it

I bought this easel because I saw how easy and fast the set up was, but I painted on a sandy beach and the legs stopped telescoping. I worked with it and got them to go again but then during a competition this summer one would not go down all the way. I toted it around with the one leg half way down it would come out so I was able to finish. I called the company to see what to do and they said I had to send it in, that was 3 months ago and I still do not have my leg back. If they would just send back the non telescoping leg at least I could use it in the studio. Very disappointed for the $$$ I spent.
