Solved my problem. Easy to fit

Arrived quickly, easy to fit, working well

Excellent only took a couple of minutes to fit.

Fits perfectly, a well priced and easily to replace maintenance box. Recommended.

I hadn't a clue what this did when l purchased it, other than printer would not work without it being replaced. I was expecting it to be really expensive but it's under a tenner. It was so easy to install [another worry] and immediately everything was back working and you could see straight away an improvement in print clarity. I am going to order another so l am prepared next time.

Arrived when stated, very well packaged with fitting instructions. Very easy to fit and printer worked without a problem. Very satisfied with product.

As described easy to fit

Great alternative product. Great next day delivery/service and does the job perfectly without hassle
