denzel_lowyck I bought both the inside and the outside and I'm telling you it's a life saver! Totally worth the 23€, and extremely fast shipping for me to Belgium, took them less than a week and 7 days faster than the estimated delivery date.
I don't reccomend building this alone though, it took me over 2 hours to try to get it perfectly with only 2 hands. But I managed to do it anyway, just saying it's a lot easier when someone can hold the pieces into place.
Now that everything is in place it is BETTER then when I first bought the G930 out of the box! TOTALLY WORTH IT!! 10/10 !!
