Cassandra Hot Water Bottle, Smooth Surface Both Sides, 1.8 Litre, 5 Year Cassandra Guarantee, Colour Received Varies

I bought two of these hotwater bottles about 18 months ago, and was surprised to see the guarantee had extended to 5 years, as the previous two (same brand) had perished and split after a year, well within the then 2-year guarantee period.Over the past few weeks it has become obvious that the latest two are on their way out (bits of perished rubber in the water emptied from them) and one has just burst. Luckily I use them only to put against my back so I have only a small scald on my backside, not the major burns possible if a HWB bursts in your bed.I wrote to the address on the packaging of the previous two to enquire how to invoke the guarantee. No reply of course, which was expected as there is no mention of how to claim on the packaging (normally the case with guarantees).About to buy new HWBs from Boots, as then I can take them back for a refund if they fail.

Perfectly acceptable for the price. Comes with wonderful list of 21 things you should not do with this hwb (like use it as a cushion.) Then you realise it is called a Cassandra (the ancient prophetess whose dire warnings were not believed.) Genius.

I am taken with same day delivery, yesterday morning I saw the weather forecast for the days ahead, all artic blasts and disruption :-/ took a look at my old hot water bottle, seeing it is some seven years old, decided to order replacements and low and behold I went to bed with a brand new hot water bottle last night :-) this facility raises the prospect of JIT (Just In Time) living, what we want in the quantity and condition required, without excess.The bottles arrived in good condition, well packed and in original packaging. I unpacked one immediately, no defects were evident on the bottle. I filled it up with water I brought to the boil and allowed to cool a little, placed in my bed at about eight ish (with a pillow over the duvet where the bottle was), went to bed at half ten and experienced one of the simple luxuries of life :-) a lovely warm bed and pillow on a cold night :-) moved the bottle down to beside my feet and slept well :-)In the morning I examined the bottle (I reused the cover from my old bottle) found no sign of any leakage on either the bottle or it's stopper. There was a smell of rubber from the bottle, but to be expected with a brand new bottle.So it did what it is supposed to, with no leakage or issue.The bottle appears quite as robust as my previous hot water bottle, so I am anticipating some years of use :-)The price of these hot water bottles represents fantastic value, provided they have the longevity one would expect. I purchased two, there's a predicted Beast from the East (again) so I'm ready.

All very well for Cassandra to Create a revolutionary new stopper. Fact is that their old stopper has a serious manufacturing defect - the rubber perished after a year or so rendering the bottles useless. So thanks for the new design, but if you don't supply replacement stoppers for the existing defective ones (or even sell them cost-effectively, you have effectively ripped off customers who bought the non-revolutionised design. Not good.

I have had cassandra bottles previously I have to say this time and compared to previous purchase the quality has declined1st it is now only ribbed on one side so be careful as the smooth side does get very hot to touch2nd the thickness has changed so again be careful3rd the stopper is very flexible not rigid anymore4th this bottle does NOT hold 1.8 ltrs the older versions do but NOT this new version I burnt myself I put 1.7 litres of water in my kettle and it came up and over and got me
