A few months ago I bought two large SPUR HRX 250ml x 2 developer set from macodirect. They are cheaper in Europe (this set is $60 @ Freestyle).
After cracking open the first two bottles (part A and B), everything was fine, but then I didn't use the developer for a few weeks. When I next went to develop some film, Part B was almost completely gone. After investigating, I found some pin holes in the bottle which were leaking! I was really ticked off because this stuff is not cheap. I lost about 80% of the bottle.
I emailed Maco and complained but they pretty much told me too bad, it's your problem.
I checked my other set and everything seemed fine. I put them away in my cabinet. I just happened to look in that cabinet today and what do I find but most of Part B filling up the plastic bag that the set ships in. I cut the bag open and drained the developer into another container and the whole bottle of developer came out. What I found was the bottle was completely shattered on the bottom. This makes no sense as I haven't touched it since I bought it. It certainly didn't get knocked over.
My hypothesis is that Part B is disintegrating the plastic bottle it ships in, and after a long period of time, the bottle fails. If you buy this developer, immediately transfer Part B into a new bottle - probably best if it's glass.
I have no clue if the Part B I salvaged is any good. I sure hope so. The two sets I bought would be $120 from FS if I bought them here in the US. Apparently the set from Maco is much cheaper than when I bought it. I don't really understand the price flux.
Here's the bottles I'm talking about
Perhaps I should email the SPUR manufacturer and complain. I'm pretty annoyed.
