These M1 +coils are really good and for the price they I would say are the best horizontech coils you can get.
Now I would have given a 5 star review but I ordered on Monday morning and didn't receive them until the Friday so I have to knock a star off as I live in England and was expecting them in 2 days max, but otherwise very happy with these.
I am completely satisfied with the product, I got what I expected
I have to agree with another reviewer who said that the M1 coils are "nearly as good as the M2 Coils" Having said that the flavour from these coils is really good and my go to ones when I can't get the M2 coils.
Good coils arrived on time
