Just a word of warning about the Halfords sets. Not had problems with the sockets but I was doing some work on the Felder and there is a nut you can only get on with a spanner. Using the Halfords 13mm and rounded the blasted nut. Never slipped off it just rounded over. Checked I had the 13mm and yes but it was a bit loose on the other nut so I got the verier gauge on it. The 13mm spanner was 13.3mm. I found a cheapo Screwstation one and that was 13.1mm and successfully removed the offending nut. All of the Halfords ones were a bit oversize but the 13mm was the worst. Cheap set was consistently closer to the marked size. For general work the Halfords set has been fine but I can see why it's sometimes worth seeking out better quality tools.
I have one Halfords open-ended set bought years ago with the opposite problem - it has lumps on the tips, possibly because it was too long in the plating bath, but it might just have been badly machined*.
That means you can't slide over a nut along the axis of the spanner, which is really annoying. They look really nice and shiny but they're not actually that well made.
It's one reason I go for hexagonal socket sets now, rather than the 12-flute ones (my Draper socket set is 12-flute in the bigger sizes). Hexagonal ones have far less chance of rounding off a nut or bolt head.

* which is why I haven't tried to "fix" it - in case I break through the plating.
