Best betta food on the market! Just make sure you soak the pellets for at least five minutes in tank water before feeding your fish. You would be surprised at how large they get.

Didn't get a thorn poking through, but the valve stem is made very weak - it cracked off where it attaches to the tube in less than 6 months of use. I will not buy this brand again.

These are incredibly cheap as far as cheap sunglasses go. I knew they obviously wouldn't be anything nice since they're so low-priced, but they are surprisingly cheap quality. Very flimsy, feel like they could fall apart at any moment. I wouldn't recommend to anyone, you're much better off heading to your local Target and getting a cheap pair of sunglasses that'll last a lot longer.
