Good value

These are good value compared to other brands. They are extremely generous in size- which makes them comfy if you are bloated. They are quite bulky but good for price

These knickers have been a god send for my mum who has endometrial cancer bleeding. These knickers make sure her clothes and bedding are protected. I prefer the pink/burgundy colour but these are no longer available.

No, I don't recommend this

I read the reviews and trusted M&S quality, but these leaked within an hour. Really disappointed.

Really comfortable, soft and not bulky. Wash and dry well. Not as absorbent but happy to have more pairs and change more regularly.

I was sceptical on if these would work but now I couldn’t be without them. Wear them as a second form of protection when out and about but wear by themselves for sleeping. I sized up to account for period bloat and they are super comfy.

These pants are a very good idea however they come up quite a bit larger than expected and are quite uncomfortable. I will keep them in the hope they will shrink a bit

They have changed them.

Originally posted on marksandspencer.com (UK)

I bought the 'white mix' 3 pack (with white dots). They have changed the way they do the leg elastic - they have a thick edge and 2 rows of stitching, also the waistband elastic is different and irritating. Not sure why the change? I didn't realise, put them in my drawer and found out too late to return that they are different and not an improvement. This keeps happening, something you rely on and were happy to discover gets changed with no warning - sigh. Still wearable(needs must) but not happy with the changes.

Not the same.

Originally posted on marksandspencer.com (UK)

The 'black mix' with the leopard print pair are very good - comfortable, well fitting and good absorption. However, the other set with the white dotty pair are not a good fit - they are tight on the thighs and the elastic used in the waistband is very irritating to me.
