FNLite Means a Smaller & Lighter Bottle, with No Loss in Capacity

The Bunkerkings FNLite Carbon Fiber wrapped bottle line-up is engineered to be the lightest bottle you'll ever need. Simply screw your preferred 4500psi-rated HPA regulator on and get back to killing suckers. 

We've designed the the FNLite bottle to be up to 10% lighter and 9% shorter than the competition while still delivering the same number of shots with no loss in capacity? How do we do it? By using a proprietary DOT/ISO certified  carbon fiber wrapping technology around an aluminum liner, the FNLite shaves off weight and increases the inner volume at the same time.

With the FNLite, we've restored sanity to to bottle sizing that creates the perfect form factor and capacity for every player. Simply make your selection from four lightweight sized bottles: 60ci, 70ci, 80ci, or 90ci.

Just Love this.... Read On!
Color: Silver, Memory Storage Capacity: 128 GB, Set name: Wi-Fi + Cellular
Like knew and seems to have been powered on one time only. Apple treat it as a new device. Its spotless and works great. I have had several ipad pro's and decided to by this instead and I actually prefer it. It does everything I could do with my ipad pro 2020 and then some. Its faster, good cameras. The e-sim card works great though I do wish it had a physical sim card slow.. oh well! The battery life is really excellent, it was quick to set up via a transfer from my old device. I added a case that looks like a fancy note book and love it. This helps with drops and scratches. I have not added a screen protector yet. The storage capacity is the same as my old ipad pro, I will never use 128 gb anyways... To sum up, this gets 10 out of 10... and its a great replacement for a ipad pro!
