Pros
- solid construction
- holds cards pretty well
- lots of choice and variation
- sim card eject tool slot
- nice and small

Cons
- lots of choice and variation.. while a pro, not everyone needs so many choices
- a bit stiff at first to open but becomes easier with use

I actually love the quality of this little case. It's so good in comparison to others you can buy at not much less than £12.99. Materials are solid. Probably not going to survive a huge crush from a large rock or anything (it might though.. plastics seem strong enough and the design is pretty solid)
As I mention, 4 SD slots just feel a little too... less. Most cameras run either SD or CF cards these days. Great for drone users with microSD though. 6 cards should be more than enough.
Image is a bit misleading though, it shows 'SD' on the opposite side, at least with the product I received it's not actually capable or written on it. I'm not really sure whether it's a fault or just an oversight.
You get a small, and what seems to be decent, carabiner clip too that is a nice addition to see.

Overall, I'm giving it a 4 star. The quality is a 5 star but the design for so many cards kind of is a detriment too it. It is nice and small though. Which will help save a bit of space!
