ABSOLUTELY PERFECT - I LOVE THIS!!!
Color: Pink
I absolutely LOVE this case and the keyboard - it’s absolutely perfect in just about every way. If I had to get nit-picky and find something to give feedback on, I would say it is a bit heavy and it is a bit annoying that you have to move the keyboard forward when you want to use it and backward when you want to close up the case but I don’t care, I love it!

Quality Case
Color: Pink
This is an All in Pne case. I really like the lavender color with sparkles. It is a little heavier than expected but I still love it!

Ok, but don’t use hand cream
Color: Black, Color: Black
I like the case for its ability to house the keyboard, the pencil and the iPad in one convenient place. I find that the magnetic closure and magnets holding the keyboard are not as strong as a previous case I had purchased. The keyboard is great, I like the touchpad and the backlight colors. The cover material is not hand lotion friendly! I’ve tried water and lens cleaning wipes, and neither gets this cover clean. I hesitate to use any chemicals because the material is the type that will get sticky and nasty, and I don’t like that. I’ve included a photo of what the cover looks like after using a lens cleaning wipe. If the magnets were stronger and the cover material easier to clean, I would buy again.

great case!
Color: Navy Blue
pros; the color is beautiful. I picked the navy blue. It is exactly as the description described. It goes very well with my blue iPad. The size is very precise and fits perfectly on my iPad. The magnet that holds the case together is very strong. The iPad itself can pivot vertically and horizontally using that magnet. This works very smooth. The magnet closure for the case itself is strong and holds well. The magnet that holds the keyboard in place also works very well. Cons; when the keyboard is in its correct position, it is difficult to angle the iPad in front into the provided grooves. The keyboard gets into the way. This prevents the iPad from reaching the grooves provided. The keyboard feels very light and cheap.
The keyboard itself connected with the Bluetooth very easily. It works wonderful. I love the back light on the keyboard. The color of the keyboard is wonderful. However, as I said above, it does feel a bit cheap. But for 20 bucks, what can you ask for.
When the case is folded together with the keyboard in the iPad, it is a bit bulky. But I knew that from the previous reviews and was expecting it.
What I love most about this case is that the iPad can be removed using the magnet on the back from the keyboard portion, but it is still protected by the exterior plastic case. So in situations where I don’t need to use my keyboard, I can remove the iPad itself and know that it’s still protected overall I recommend this product.
