Bright & Pretty Hot Pink.
Color: Pitaya Red, Color: Pitaya Red
Very pretty and bright. It’s thick and great quality. Strong grip and doesn’t come off easily. Easy to clean when it gets dirty. It also has a nice backing. I prefer the transparent bright pink backing than the clear version. I love the strong magnetic for when I position it upwards. It can be positioned downwards too.

Very protective iPad case
Color: 1-Navy Blue
This MoKo iPad case is excellent! It fits perfectly and provides great protection without adding bulk. The navy blue color looks very sleek, and the translucent back shell is a nice touch. It’s super magnetic, with great padding. The smart cover works flawlessly with the auto wake/sleep feature, and the cutouts line up perfectly for Touch ID. Lightweight, durable, and a fantastic value!

Quick install of cartrage and software for printer counter
At first had trouble. The instructions that came with it would not reset my printer. I emailed the seller and about 24 hours later I received another set of instructions that worked on my printer. The price for 4 is great I now have a good supply of back ups. I have and do recommend this. It was an easy install of the ink tray, good quality and fit perfectly. It is compatible with several printers.

Easy process
I only used it once, I don’t know how the other 3 keys are supplied to work because I did not see any counting bit it work perfectly. It was super easy, my only issue is that I had to download the driver and restart the pc to make everything work out but the process itself is pretty easy. The printer work like new and the installation was easy too.
