I struggled with another product (which shall remain nameless). I was never strong enough or coordinated enough to change the filter. This product, however, is a DREAM to use. And the water quality is excellent. I've used for a few years now and with no problem or hassle whatsoever. (Of course shipping of the filters was difficult at the start of the pandemic, but that is not the fault of this or other suppliers.) I heartily recommend this product!
