| Remark | When using the Big Operating Cylinder, the stroke amount of the cylinder decreases, so please adjust the stroke as necessary. 1) Be sure to clamp the hose with a hose clamp to prevent air from entering before removing the standard operating cylinder. 2) Fill the Big Operating Cylinder to be replaced with Brake fluid, remove air beforehand and connect it to the Hose. 3) Even if you do 1), 2) work, air enters the piping. Once the air enters the piping, the pedal stroke and feel change. Because it is difficult to remove air from the thick diameter U-shaped pipe etc, please bleed sufficiently. 4) To facilitate the work of 3), air bleeding by vacuuming is effective (Please use the U-shaped pipe dismantling adapter attached to the NISMO clutch hose). |

Lightweight oil that fits into a simple routine
I started using this oil as part of my regular skincare routine, mainly applying it to areas like my arms and face after showering. The texture feels light and spreads easily without leaving a heavy residue. I noticed it absorbs fairly quickly, which makes it convenient for daily use. It also has a mild scent that is not overwhelming. I like that it includes plant based ingredients, and it leaves my skin feeling soft after application.

It works!
Item form: Tablet
I have used this once about a month ago. Did as the directions said, using 2 tablets. My garbage disposal smelled awful before using. These took the smell away and still has had no bad a smell after 4 weeks of using!

Good Product, Works Well Even Without Much Foam
Item form: Tablet
These Bastion garbage disposal cleaner tablets are effective and easy to use. They don’t generate as much foam as advertised, so if you’re expecting a big foaming action, you may be a little underwhelmed. That said, they still do the job well—the disposal smells fresher, and the citrus scent is clean without being overpowering.
Overall, a good product that keeps the sink area smelling nice. I’d give it 4 stars mainly because of the low foam, but it’s still a solid buy.
