I ordered cleaner bags from SPARES-2-GO against this listing, which from the description and illustration I understood to be for GENUINE NUMATIC HEPAFLO bags - ONLY.
A few days later I was disappointed to receive pattern/aftermarket bags, ie. NOT Numatic, NOT Hepaflo (and not in a box, either); I am unable to comment on the quality or performance of these bags as I returned them the next day.
I received a refund of the full invoice amount (from Amazon) about a week later, following which I then requested from the seller reimbursement of my return postage costs. (As I returned the goods direct to SPARES-2-GO about 5 weeks ago it seems unlikely that this will ever happen.)
Clearly, I am not the first buyer to have been misled in this way, but unfortunately 20 of the 22 other reviews available are almost meaningless as they fail to name the ACTUAL supplier.
Subsequently, I have ordered and received the genuine Numatic items from the host site - Amazon themselves - and for just a few pence more than the original order.
Therefore, to summarise - if you want GENUINE Numatic Hepaflo bags, order from Amazon.co.uk; DON'T order from SPARES-2-GO unless you want to save a few pennies and/or are content to receive non-genuine bags merely masquerading as the real thing.................
