Leaked immediately - do not buy

No, I don't recommend this

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

Comfy and look nice

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

Great product

Yes, I recommend this

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.

Comfy and they seem to be ok for day 3 onwards. Not super heavy days.

A bit disappointed.

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.

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.

Yes, I recommend this

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.

I wasn't convinced about using period pants but after trying them, they are amazing, no leaks, easy to wash and comfortable.

Not the first time I've bought these for my granddaughter. She loves them. They help give her confidence especially on her heavy days.

Comfortable and absorbant.

Yes, I recommend this

These are very comfortable and absorbant. I have been wearing them both as a back-up with a menstrual cup and on their own overnight on occasions. I'm definitely going to buy more for the future.

Fantastic

Yes, I recommend this

So comfy to wear and has great absorption. A lot better than traditional pad as I usually get nappy rash with them.

New and improved - these are so much better than the previous ones I purchased. They fit better work better and are easier to wash and dry - thanks M&S for giving me my confidence back. Any thoughts on introducing a urine equivalent?
