Also bought the HP wireless one 3 or 4 years ago and have never had a problem. As I'm quite a light user I didn't go for the instant ink option.I usually buy HP ink but have used the Tesco own brand which was as good as HP own brand but obviously cheaper. The printer does tell me when I use a non HP ink though.I bought ink from Rymans in the High Rd recently having seen a special option online. after checking the price in the shop, I bought online from Rymans using click and collect as it was £12 cheaper than the shop. I laughed when I went to collect, as after I showed the "ready for collection" email, the assistant reached behind and took one from the rack of inks. I paid £25 for both black and colour pack whereas it was £37 in the shop, so always worth a check.
