An Ah Pek visited RPC for a blood pressure reading a month ago. He just bought a bunch of plastic filaments to use with his grass cutter. I only requested for one filament and did not charge him anything.
My super cheap bottled water pump finally showed up a few days ago. Sadly, the quality is really low. It is too loose for the standard hole on the bottle cap, while the one RPCNs are using (RM40+ Spritzer) fits snugly.
When you unplug the microUSB cable, the charging port comes out with it.
The included tubing is likewise a thinner silicon variant, so it kinks easily. Water flow rate is significantly reduced when kinking occurs.
And then I put the stiff grass cutter filament into it, and the kinks straightened.
