We’ve bought many less expensive pop ups over the years - they don’t last and are difficult to deal with.
This popup is very well made and can actually be set up by one person. The fabric is not going to rip or fray and the metal is not going to crimp or bend. Also the Velcro is very impressive. Sides, as many as you want, are easily ordered from the manufacturer (we ordered one).  The case and wheels make transport on the beach very easy.
