Formula To Calculate Rate Of Return On Stock

5 stars! Stable and very easy to adjust level with slider on.

Our prior supplier was out of stock on the cartridge and B&H came through with one at a fast rate to keep us working.

I am hoping these will be back in stock as I use a lot of these and love that the failure rate is very low - maybe 2 out of 100 or so - not bad compared to outer brands.

I like this because of the concentration ratio. A little goes a long way! The color changes when the formula has been exalted.

Feels solid, a great add-on for Formula and GT racing.

Buy yourself some peace of mind with a well-regarded brand and a proven formula.

Tried & True formula that lasts a long time. I use it for all my B&W work.

I like Ilford's products when it comes to film and developing chemicals. At first I had issues trying to calculate how much powder to use to make the amount I need to use for developing ( so I could maximize the shelf life)

[This review was collected as part of a promotion.] Not the ink's fault it ran out way too soon! I didn't calculate the "small" amount of printing our 2 person household actually prints! But works fine in my HP printer, all the way to the last drop!

I wasn't sure if this was going to work well or not but I find it does make it easier to calculate the lighting in my studio. It's very easy to read and use. Helps with realizing the light needed and helps us understand the quality of light. Overall good product that I would recommend if you're thinking about it.
