Helios 44m - Is this £50 lens really worth it?

I saw this lens popping up in my feeds constantly, and at only £50 I thought why not give it a try? I spent a day on the Isle of Tiree in Scotland, using just this lens. This lens has very quickly found its place in my standard lens kit, and I've started using it over my nifty 50. It is over 40 years old and manufactured en masse in the USSR, but this glass is still super functional. It finally taught me what everyone means when they say that vintage lenses have more character, and has probably awoken a new hoarding habit for vintage lenses in me.
