Works as well as OEM.  When painted with color matching paint it is indistinguishable.

Works as well as the original.  Those that say fragrance is week are probably not using the sandalwood sticks as diffusing wicks.

Works as good or better than OEM ink, and is definitely less expensive.  Shipping was quick, and followup was great.

OEM replacement at a competitive price.  Must use OEM for this x7550 or it says the ink cartridge is empty every print job.

My son lost my original so I bought this hoping to save a few bucks. It seems to work as good as the OEM, and the quality is fine. I noticed no difference in charge time.

Parts work well with the roomba, just as good as OEM parts. The spinning brush usually breaks first and requires replacement fairly often so I wish these accessory kits came with more of those than the other parts.

Slipped right in to place and worked.  Prints as good as OEM

Seems to work well. Looks and operates as well as oem. Can't really ask for much more.

Not the same quality as OEM, but close enough and the price was right. Makes color coding the front and rear nice and easy.

Excellent working with a fraction of cost of the OEM product.

Every bit as good as the OEM at a fraction of the price

Works as intended.  I love the fact that this is an OEM.

Paint color is an extremely accurate match to the manufacturer's 1F7 original color. The only reason I don't say "perfect match" is that touching up a scratch still leaves signs that there is some unevenness in the paint coat surface, which frankly is not the fault of the product here.
The only con I see is that the brush head tends to suck out more drops of paint than necessary for a single stroke, so you end up wasting a few drops (dripping off) every few strokes.

works as well as original manufacturer's ink. Buy this and save money/the environment. Send your old cartridges back to seller with enclosed postage-paid bag. Great!

Looks OEM quality. Heck, the original stickers peeled themselves off. These should last at least as long for 1/3 the price.

works as advertised. if your paint has "rail dust" on it this will dissolve it.

Flawless match--my experience is that for a few dollars more, it's always to buy the OEM items, especially the highly visible paint.
