I've had a mixed experience with Lidl/Aldi cheap electricals.
Medion Car Stereo for £40 - sound quality pretty good, but the RDS refuses to retune for traffic announcements on other stations, it likes to tune to a distorted frequency for Radio 4 instead of a better one, and switching from Radio 4 to local radio can leave you listening to static for several minutes while it thinks about what to do.
Silvercrest Wireless Mouse cost me £3 from a Lidl sale. Works well enough, but is heavy and not very ergonomically designed.
Lidl LED rechargeable inspection lamp. Is about a foot long, has LEDs along it, charges from mains transformer or car adaptor. Amazing. Very bright, runs for many hours on one charge. Excellent for attics/dark sheds/car breakdowns/poking around inside a PC under a desk. Was around £8 I think.
I've tried various Lidl rechargable batteries over the years, they're a good price (£3 for 4xAA 2500mAh) but they don't seem to last for very many recharge cycles before failing to charge or losing their charge very quickly.
Sorry, wandered off your original topic there Kitz
