Purchased a skylounge when they first came out. Sometime during the first season some how managed to bend the bolts in the corners...? Send it back to BD and they replace the entire thing (not just the bolts) which was rad on their part. 
  
Overall the ledge can be way faster or way slower than setting up the Cabana... it mostly depending on you. Some ample practice (free hanging, on a slab, in the dark, etc etc) should ensure you dont epic 
  
Footprint wise they are roughly the same dimensions as an I tent (in fact an I tent will fit on the ledge) so if an I tent is too small for you I would consider a larger ledge. Shoot me a PM if you have other questions
