Is it dangerous to keep driving with a worn pulley?

A pulley that fails completely can throw the belt off entirely, disabling the alternator, power steering, and other belt-driven accessories — repair before this happens.

Should the belt be replaced along with the pulley?

It’s a good idea to inspect the belt at the same time, since a worn pulley often causes accelerated belt wear.

What is the pulley made of?

Steel or reinforced composite, depending on its position and load.

I ordered a Heater Blower Motor Resistor for a Toyota Avensis. Delivery took eight days from Latvia to Ireland. I installed it, and everything works perfectly. I wish this company success.

No complaints about Evro Trans itself, everything's fine. But the delivery..... It felt like the order was being carried by turtles. 4 days from Riga to Daugavpils. Judging by the tracking, the parcel just sat somewhere behind a shed for 3 days, then they found it and delivered it the next day. I think that's why I won't be ordering there again.

Bought a front fender for my car. I liked it! After payment they sent more than 20 photos of the problem areas, and it was packed very securely - took a while to unwrap.
