Its the old old story, you get what you pay for...
Not always,
I bought a Roberts Dab radio for £120, went t*ts up after 18 months, Curry's told me to do one and I was left with a £50 bill to have a new transformer fitted (the thermo switch had failed).
The bloke told me I had paid £120 for a badge, they are all made the same now in the far east, Roberts is not the great British make we once new.
I also have a Sebo BS36 which also after just 2 years I keep having problems with and my Sebo duo has just failed!
