SanDisk Ultra 64GB SDcard

My 2GB sd card has no problem working in my iMac, in my PC laptop and in my Samsumg Android smart phone.

My 32GB sd card has no problem working in my iMac, in my PC laptop and in my Samsumg Android smart phone.

My SanDisk Ultra 64GB SDcard has been nothing but problems.
It won't work on multiple platforms.
Fine. In the end I decided to use it just as a bacup device on my iMac alone.
Problems: It keeps unmounting itself and then there a faff to remount it.
What a palavar!

Sainsbury's own brand food flasks

I bought 2 of Sainsbury's own brand food flasks. one functions as expected - cold surface, when containing superheated soup, remains hot for hours.

the 2nd flask doesn't function as expected - warm surface, when containing superheated soup, Does not remain hot for hours, not even warm.

visibly the flasks are identical, they even weigh more or less the same. so why the difference in effectiveness?

Book binding

Why make such insubstantial books?

It certainly spoils the reading experience.

Sainsbury's Herbal Teas

This is the second time in which tea bags have been glued to the box itself, so that, on opening the box, two bags are ripped open, causing a mess to clear up, and the loss of two tea bags.

The first time this happened I actually contacted Sainsburys, expecting some kind of recompense.
All I got was an apology letter.

From now on I shall post all my complaints on social media.
