Is this is a wise buy?

Hi Everyone! I was looking for an affordable case for my s4 and I came across this promo at amazon. I wonder if there's anyone here who have tried buying accessories from this company. I post this question as I am planning to buy 4 pieces of smartphone accessories from the maker of this case. I wonder though if its a wise buy.

Should I prefer otterbox or minisuit? I know otterbox is a good choice though there products are quite expensive. Please feel free to comment below or to contact me directly if you have any suggestions.

Thank you so much.
