Question: How bulky does it feel? And can I charge my tablet without opening cover?
Document: Case fits perfectly. Able to charge the tablet without removing the case. Very comfortable to hold. Like that the Table turns on when I open the cover. Nice feel. Only wish it was a little thicker for more protection.
Perfect. Fits well. Looks good. Even offers a decent amount of protection for the screen being compressed. Can charge without opening. I dig it. And it's not $70. Can't beat it.
Like the name implies, it's really slim! Doesn't add any bulkiness at all. The magnet works and I love the fact that the sides are accessible so I can change the volume without having to open the case. There's a hole for the charging port as well so you can charge it with the case closed. Front and back material is like a faux leather feel and the interior hard case feels just like the backing of the Xperia Z tablet.
I bought a similar one that was about $5 cheaper but was not happy because it was bulky and just wasn't as sleek. This one is perfect, it's very similar looking to an iPad version except the back actually snaps and covers the back of the tablet. So your protected (somewhat) from the front (screen side) and the back as well. It's not really going to protect from drops and such but certainly from getting scratched. The inside cover has a very nice micro fiber feel to it.
Pros:Slim, price ($18), fit and finish, closes with magnets, folds to hold tablet in landscape, can charge with cover closedConsAdds a little heft but most covers wouldA few have complained that the tablet can't be charged while cover is closed. It seems they addressed that. Mine came with an opening for the charger. I personally wish there was a way to also make it stand up portrait but I guess I cant have both (slim elegance and total  versatility).
I really like this case. It's slim so I never feel like it's taking up a lot of room in my purse, lightweight, the three paneled side is sturdy and keeps the tablet standing.Only con is that you cannot charge it with the top closed. For some reason they made it so that the charging port is on the folded side of the cover and so you have to keep it open and exposed while its charging.
You can also use this charing port with a simple aftermarket USB adapter, without the need for the complete dock, and it is much, MUCH more convenient way to charge your tablet because you don't need to open the waterproof flap like you must do with regular microUSB port. However, this case yet again COMPLETELY covers this charging port with the cover closed, so you must either keep the cover opened during charging process OR manually cut the hole yourself for using that charging port.
Very nice case. I love the way it looks. Since I have a stand charger, I have to remove it each time from the case to charge. It is a  little hard to get out of the case each time. I would still buy it again, since It can be plugged directly to the normal charger without taking it out of the case.
This case attached easily to my tablet. It's not too bulky and protects the right places on the table. The only thing I would say is the plastic cover over the usb charging port is a bit of a pain to place when charging the tablet with the cover closed. I am afraid it will break off when I close the cover sometimes.
For the given price, I would say this is the perfect cover for protecting the Xperia Tablet Z. Look and feel is very good, doesn't feel cheap at all.
Answer: I don't think it feels bulky at all. It does add a little bit of weight to the tablet, but I am super happy with the product. I always charge the device with the cover closed.
