Brilliant little lights, for a tiny price
These are so handy!
You get a batch of 10, and all 10 worked in the batch I got, although one of them needed a little bit of an extra push to get it to light up (to be honest, for the price they were I would have been satisfied if half of them worked).
The light is surprisingly good. Just give them a push on the middle and they’ll light up. Alternatively, you can use the tiny little switch on them to keep the light on (incase you need both hands for something). Battery is also excellent… left one on overnight by mistake, and although a little dimmer, it was still shining the next morning!
