First, I bought the version of this case made for my new Lenovo IdeaTab A3000 7" tablet. I'm not sure to what extent these comments will apply to other versions.
The case is attractive (at least, compared to all the others I found) and seems like it's well-made. Some particularly praise-worthy attributes are the fit and the fact that it doesn't block any of the ports, speakers, or even the rear-facing camera! I have not dropped the tablet, but I think the case could offer some reasonable protection, depending on the angle & location of impact. I have not carried it in any way that would put pressure on the screen area, so I can't say whether the case might eventually leave marks, there.
What I can say is this: a major requirement I had for a case was the folding feature, so that I could place the tablet on a table, at an angle. I do this for use with my bluetooth keyboard, and rarely touch the screen when it's setup like this. Unfortunately, this seems to be the most poorly executed feature of the case. It works as advertised, but there's a plastic flap you must bend. When the cover is closed, this flap could rub against the screen, possibly leaving marks. Because of this, I am careful not to bend it out too far, which makes the operation more awkward and the setup more delicate. Also, the case sags a bit, when the tablet is setup in this orientation.
I have two minor complaints, as well. First, the case lacks anywhere to put a pen or stylus. I hate reading on a dirty screen, so I use an amPen Hybrid Stylus, which I really like. I can clip the stylus on the outside of the spine, however this leaves the tip exposed to damage and dirt (since the stylus lacks a cap or any other way to protect the tip).
The second minor complaint probably applies to most cases, and that's the bulk and weight they add. Normally, this isn't a big deal. However, it can be a real problem for reading e-books, in a hand-held fashion. If the case had a better mechanism for removing/inserting the tablet, I'd probably take it out of the case for this type of usage. However, doing so takes a bit of effort and I fear that continually removing and re-inserting the tablet will cause the fit of the case to loosen.
I'm not sure there's a better option, for my tablet. Most likely not one I'd prefer to look at, compared with this one. I don't regret buying it, but I wish it were a bit better in the areas I mentioned.
