Positives:
+ Protective Case looks quite robust and looks quite good
+ USB cable / car adapter are sensible additions
+ Price
Negatives:
- A protective film had a scratch ('m probably just bad luck that I've caught this)
- With car adapter it is very tight in the case. I would not do that to my 3DS and therefore possibly wrap separately.
Conclusion:
On the whole, one can nothing negative to say. Purpose is fulfilled and therefore there are very good 4 stars from me.
But who puts on best quality value of the accessories will have to buy better einzelnt together - but end up accordingly in a much higher price.
