I have mostly lab apparatus used in Physics. Also avalible, both mechanical and electrical workshop facilities for manufacture or repair of lab equipment, and complete experiments. Please email if you may need items made, or adapted. Based in Euston, Central London. Shipping worldwide.
The potentiometers were shipped in soft packaging and without tracking.
So the potentiometer contacts were bent during shipping and it was not possible to track the shipment and the shipment arrived with a delay, which was annoying.
So these things could be improved for next time, but otherwise it is OK.
In communication, the seller seems like a nice person and responds quickly.
