ALDI shoppers are praising the supermarket’s £3 tap cover that stops outdoor pipes freezing over.
The nifty gadget works by covering taps with a hard outer shell, which is made from polypropylene and a foam inner rim.
You'll want to make sure it covers all exposed pipes, as well as your tap, for it to really be effective though.
This is because frozen pipes can be costly to fix.
Consumer champion Which? says the average cost for calling out an emergency plumber is around £100 to sort a frozen pipe.
But this doesn't appear to have been an issue for Aldi shoppers, who've been applauding the tap cover for keeping their pipes intact.
Posting a picture of the cover on the Aldi Shoppers UK Facebook group, one customer was met with a flurry of approval from fellow shoppers.
She said: "I bought this outside tap cover yesterday. I don’t know if this will work but I think it’s a brilliant idea if it does."
One shopper responded: "We've had ours for several years now and never had any problems."
Another said: "Bought one of these from Aldi a few years ago. Still working well."
A third commented: "Had ours a good few years now from Aldi. Brilliant."
Sadly, the tap cover - which costs £2.99 and measures 10.5cm by 15.5cm - is sold out on the Aldi website - but you can still try your luck in stores.
Aldi has around 890 supermarkets in the UK - use the online shop finder tool to find your nearest one.
This is the cheapest tap cover we could find, with Screwfix starting prices costing £4.19, plus £5 delivery or free click and collect.
But there are most cost-effective ways to keep pipes from freezing.
You can save money by buying foam tubing insulation - which works by being fixed in place on top of a pipe - for less than £1 per metre.
The cheapest in a previous round-up by The Sun costs 70p per metre from Wickes.
Meanwhile, Screwfix sells identical foam tubing for 72p per metre.
