Lidl.
They still had some in here last week. I bought one years back expecting it to die soon. Still going and it’s good enough to do brake discs on lorries. Tested it against a couple of others and within a degree or two they’re the same.
£7
If they still have any tomorrow happy to post one of you want

I bought this fella a few years ago for a tenner. Now a princely £13 but it's lasted several years, so....

Only thing I’d say, unless they’re different now, is the trigger is really sensitive and it’s got no auto off.
I got fed up of dead batteries when I went to use it and cross drilled the trigger and put and R-clip through.
Other than that, can’t fault it.

i went for the 1000f due to having the wood stove
sometimes id wished that i had bought the more powerful 2000f instead for what it was worth the 5.00 extra for it
mine has an on/off button and also a hold the temp icon i can switch on/off comes in handy when showing the temps when testing the stoves

From what sort of 'distance' can this item take the reading?I bought this fella a few years ago for a tenner. Now a princely £13 but it's lasted several years, so....

I have one of these
And a cheaper Ebay special - the martindale is a bit more accurate. Remember the reflectivity of the item you are trying to measure can have a big effect as well.
Very useful for checking on AGA/Rayburn oven and hob temps etc. Loads of uses I use mine quite a bit.

Good point - mine seem to be fine at 6 foot or so - never really tried further away.

The further away the wider the area measured, so pointing the dot at say each plug lead to check the firing from 6 ft away doesn't tell you much.

That yellow one looks identical to a blue ex-Aldi one I have (was only about £12 as well).
They do specify a restricted top end, something like 250C but the Aldi one goes way past that, I've taken readings from our calibrated oven at work at over 600C and it agrees with the oven temperature controller.

Sometimes got to be careful how you aim them - I was trying to get an indication of temperatures on a pin chain in plant, carefully lining up the red dot . . . took a couple of strange readings to work out that while the dot was on a sprocket, the temp sensor bit was carefully checking the mesh guard in front of it 
I'm not convinced of the accuracy of cheap ones, and you have to be careful of the actual surface finish, and colour, affecting the reading - but as an indication, they are okay.
The one I bought from Aldi to assist in balancing my heating system most often gets used to send the cats slightly crazy . . . along the hall, up the curtain,leaving them hanging, staring at the red dot going across the ceiling

I use mine on HGV brakes to check for bind.
It’s good enough to give one degree difference.
I’ll often get one degree difference on diagonally opposite wheels as they’re on different systems.
If they’re all 9or 10 and one is 20
That’s what I’m looking for.
Horses for courses
@bricol has guessed what i am doing. We have recently installed our Rayburn and thermal store and I want it to set up the system and roughly check the calibration on the thermostats on the thermal store etc so we can make sure the pumps are coming on at the temps we want them to. So pinpoint accuracy isnt too important. Reading within a couple of degrees would be nice.
Interesting reading about the surface colour and type making a difference. How would you measure the surface temp of copper pipe/cylinder?

I stuck a piece of black insulating tape to the pipe at the same height on all radiators. I also aimed the cheapo Aldi device at it from the same distance on each one.
Aiming the same device at painted, bare and tape on the same bit of pipe got different readings, as did distance - and when I was running around the house checking as things came up to temp, I was getting nowhere - hence trying to get readings from the same criteria on each one. SO I guess if all you pipes are the same finish, then comparisons to each other will work fine.
We use rather more expensive ones at work to monitor temps as we run new machines in prior to dispatch - results can be worrying if operator isn't consistent in how they use it. Usually different to a contact type thermometer stuck to it.
My lidl one auto power offs, maybe they updated it.
Can confirm it's really good for the cash
(check max temps , my lidl is around 300 - 400 deg c max)
