Ferrea Competition Plus Valves have built a reputation as the industry's most reliable extreme duty valve. To manufacture the valves we use special aerospace quality alloys, including the EV8-Z18, which provides high tensile strength. An exclusive two-step slow forging process ensures proper grain flow and virtually eliminates any damage to the material structure. The valves are then heat-treated and stress-relieved over a 48-hour period, which is the crucial base of our molecular integrity. These valves feature avionics-quality hard chrome along with a specially applied hard tip.

good so far!
Color: Black
Seems to work fine so far. The last one - different brand - had a bad connection and Im hopefully as I do always find Anker to be of good quality.

Great Slim iPad Case – Secure Fit & Easy to Use
Color: Black, Size: ipad 9th/ 8th/ 7th gen 10.2 inch, Color: Black, Size: ipad 9th/ 8th/ 7th gen 10.2 inch
This is a really nice iPad case and worked perfectly as a replacement for my old one that was falling apart.
I have an Apple iPad 9th Generation (10.2 inch), and this case fit perfectly. The cutouts for the camera, volume buttons, power button, and charging port all line up exactly as they should.
The iPad snaps into the case easily by gently pressing it into the rounded corners, and once installed it feels very secure with no slipping or falling out. The case is very lightweight also.
I also had no issues accessing or using any of the buttons while the case was on.
One of my favorite features is the automatic sleep/wake function—closing the cover puts the iPad into sleep mode, which helps save battery life.
I chose the black version, and it has a clean, simple look. For the price, I think it’s a great value.
Overall, this is a slim, functional, and well-fitting iPad case that I definitely recommend!

Good case
Color: Navy, Size: ipad 9th/ 8th/ 7th gen 10.2 inch, Color: Navy, Size: ipad 9th/ 8th/ 7th gen 10.2 inch
Amazing color and durability, great closure, not a lot of padding but I didn’t need it. It does not have the pencil holder but is a great iPad case over, easy fit and button accesses

Good cover for the price
Color: Black, Size: ipad 9th/ 8th/ 7th gen 10.2 inch
Perfect fit to my 9th generation iPad. It was easy to install. The back is plastic which I haven’t seen. It does what it says as far standing up with the foldable back. Seems like good quality. I gave it a 4 because I don’t know how long the back with last since it’s not standard backing.
