Absolutely fantastic things. Couldn't be without mine. Hot water bottles are so yesterday (and so dangerous. I've still got a nasty red shiny blemish on my leg where I burnt myself on a hot water bottle about 15 years ago! I don't think it'll ever go away now
)
Yes, the ones with a skirt are great. Mine though is just a tads narrower than the mattress and so often "pops off" one corner in the night which is annoying. Perhaps measure up more carefully than I did! Lesson learned. Maybe!
Finally, I once saw an offer on a shop door (I remember it was in rural Staffordshire!) maybe 10 years ago for testing of electric blankets by the local Fire Brigade. Seems very sensible. One Saturday in late summer, you could take yr electric blanket down to the local Fire Station and they'd give it a basic electrical safety test. The snag was that if it failed, they binned it there and then! You weren't allowed to take it home. The poster warned exactly that! But what a sensible idea. Does anyone know of something similar? In Leicester, where I live, especially!
I imagine that they can be highly dangerous if the cabling gets worn, scuffed or brittle.
I guess "worn, scuffed and brittle" is not a bad description of how I fee this morning. Not up yet. Snuffly nose. Typing this on my laptop in bed
