This is an attachment for a Takagi faucet.
You attach it to the faucet and then connect a watering hose to use it.
The description in the photo is a snippet from the internet. It is not the exact same product, so the shape is different, but the usage is the same.
I tried fitting it onto my faucet, but decided I wanted a two-way splitter instead, so I removed it. It was only used for a short time. It has been stored indoors since then. The packing is not deteriorated. It has been cleaned.
There is no instruction manual.
Daily Cleaning: Use a soft brush or damp cloth to gently wipe away dirt. Avoid harsh chemicals. For mesh areas, use diluted mild detergent and a soft brush.
Drying: Air dry in a cool, shaded place after cleaning. Avoid direct sunlight or high heat, which can cause fading and glue deterioration.
Storage: Stuff with paper to maintain shape when not in use. Store in a dry, ventilated area to prevent mold. Rotate between multiple pairs to extend lifespan.
Usage Notes: Designed for basketball. Not recommended for hiking, long-distance running, or other specialized sports where different performance features are required.
The product does what it’s supposed to do. Nothing extraordinary, but it performs its function well. Delivery was quick and smooth.
