The app was easy to use, it worked well with my other apps like Apple Music etc., I liked how they included all of their services in one place which made things easier for me as a user! There wasn't much that i disliked about this product but there were some minor issues here or there. It would be nice if you could see more details when purchasing an item from them (like what size your phone will need). Definitely try using any products sold through hunangaojiejin data technology first before making purchases otherwise you may not get exactly what you want/need. They helped us figure out our needs so we can purchase items at fair prices.
