### ⭐⭐⭐⭐⭐ Happily satisfied
            
*by J***D on June 2, 2017*

Sinotop Waterproof Dry Backpack Double Shoulder Straps Bag for Rafting Hiking Boating Fishing Camping Floating Big 30LI was able to used this bag twice, last weekend and just today.  I had received this bag once before and was unhappy as there were hole defects in the product and that questioned my on the durability if a hole was caused by the fold. Giving it a 2nd try, I was skeptical, as there were no holes visible and there was a comment from 2016 made me put this to a real test.  I put this bag through 3 tests to ensure that this product was durable enough for my needs.  First test: fill up the tub by using the shower and putting the bag underneath the falling water. I put newspaper and mail in it with my snorkel mask gear and a towel to use as testers if water was to leak through.  Second test: take it to the beach and use it while stand-up paddle boarding and today was the strap it down on the kayak and have it with me on my 2 hour kayak fun.  IT PASSED ALL THREE TESTS SUCCESSFULLY! Since I own 4 other Waterproof Day bags from other companies (yes I love all types of bags), I did notice this bag seemed slightly shorter when opened however; the width was bigger making it equal at 30L.  I like the fact it was wider in width and shorter in height compared to the usual slim in width and taller in height.  This enabled me to wear it while kayaking at one point today and comfortably as well.  I love the color of the red on this bag was a solid bold red not dull, which is one factor I had in mind when shopping for more dry bags.  The blue is looking enticing and would buy this bag as a gift for fellow water sports enthusiastic.
  

### ⭐ VERY THIN PVC
            
*by T***O on August 5, 2017*

This product is made of VERY thin PVC.  This is not a product that will hold up.  In fact mine came with multiple holes in it when I opened the box so I don't know how it made it through quality contol to start with as two of the holes were obvious and not from shipping.  With the holes, the bag is not waterproof.  Will look to spend more money for a thicker and higher quality bag.  This is only the second item I have ever had to return to Amazon after years of great service and products, this product though is junk in my opinion.
  

### ⭐⭐ External pocket poorly designed and held on only by glue ...
            
*by C***S on August 13, 2017*

External pocket poorly designed and held on only by glue.  Straps kept coming loose when wet. External pockets very small.
