Fair warning when you order from zandparts.eu expected it to take some time. I ordered two parts from them which is priced very fair in my opinion. However, they get you the real deal Asus part and if they don't have it in stock they get it from Asus. By the way asusparts.eu, and zandparts.com is one in the same company. They're out of Sweden. I ordered my parts on May 3rd, 2019 and just yesterday June 14th, 2019 I got the confirmation and the tracking number that it was shipped. I'm okay with that because I know I'm getting the real replacement parts from Asus. I'd much rather support a reputable company that gets their parts directly from Asus.
I did inquire about my parts after some time and they assured me and let me know exactly what was going on. They are very courteous always replied to my emails so far it's been a pleasant interaction with Zandparts. Which in return makes me want to buy Asus products In the future when upgrading or buying new products smart move on Asus, knowing that I can get replacement parts fairly easy if you have the patience.
Once I receive my parts I'll give you an update I'm pretty sure they were packed good granted it's only a flex cable that connects the board to the screen and a camera ring assembly two very small parts each part was under 10 euros/dollars. I paid more in shipping then the parts themselves haha. I'm okay with that being that I live across the pond US.
