Nitrous Express Single Entry Billet Crossbar Gasoline 50-300 HP Jet PackNX Jets are manufactured on CNC equipment, and are guaranteed to be within . 0005 of specified jet size. In recent testing, using the same jet size, NX jets out flowed the competition by 35%! That's right 35% more flow through the same orifice, how you ask? The NX jet was designed to be more than just a hole in a piece of brass; its contoured inlet and multi stepped outlet allow turbulence free flow with no restrictions. Certificate of Origin Warranty

Continent for freshening up your smile
Size: 40 Count (Pack of 1)
These Crest 3D whitening strips are seriously effective! I noticed a difference after just a few uses—my teeth looked brighter and cleaner without any harsh sensitivity. They stick well and stay in place, which makes it easy to go about my day while using them. The results feel professional without the expensive price tag. Definitely a simple and convenient way to freshen up your smile at home!

The strips work great!
Size: 40 Count (Pack of 1)
It's a great product that works. I left the strips on for 2 hours. And my teeth were so white, I decided not to use the light. I drink 3-4 cups of strong coffee everyday, and they are still really white (after one application over two weeks ago). My gums were a little sensitive after 2 hours, but that only lasted a few hours after usage. Just be aware if you leave on more than 60 minutes. Then brush and rinse really good. I use their "brilliance" tooth paste as well.
