I bought this to try to be more productive at the beach. It does a great job keeping out sand; I haven't brought it in the ocean with me, but it seems to be constructed like the dry bags I would take camping and diving. I never taken it out of the case. It is very easy to use in the case and keeps it protected from everything. I especially love that it has a port to use earphone while keeping the case closed and waterproof.
Absolutely no complaints with this product. It works well and allows me to bring the ipad into the bath. Love that it has a headphone jack for waterproof headphones. Others have suggested bluetooth headphones for these types of items, but I have yet to find truly waterproof bluetooth headsets. Using a cheap pair of waterproof earbuds has been great with this case.
