The stylus worked beautifully on an old Nexus 7 tablet. Much better and more precise compared to using a fingertip. The cover was purchased for an HP 8 G2 tablet that is 1 mm larger in height and width than the Trio 7.85 tablet. The corner holding brackets are held to the cover with black elastic, so it will fit in fine. The cover fits exactly into the large pocket of cargo shorts. It looks and feels well made. I was really glad to find this heavily discounted to $4.99 at the local Kmart, since it was exactly what I needed and it included some nice extras.
