I've been after a decent set of hex keys for a while. I bought some T bar ones a few weeks ago and typically just came across these. A set with a really good chunky handle, ball end so even easier, for the knock down price of £3! Aldi of all places. Get down to your local. Worth it if they've still got them even at the full price, can't remember what that was tho.
Got mine this morning. You can't argue for £3. I also managed to pick up a new door bell in there. I've been putting off fixing the current one for a year
I have a set of these and managed to break off a ball end but it was probably me being ham-fisted. Otherwise they do the job.
