I got several grades a year ago from super thin to medium and all of them got thicker and thicker until they were useless. Forgot the brand, sold by an asian person in California.
I have used Stick Fast and Hotstuff for a long time. I've had only a 1/4 of one bottle of medium Stick Fast go bad in maybe 15 years.
A few months ago I bought some from Mercury Adhesives, made and bottled entirely in the USA - I was impressed with their information and product: Mercury Adhesives
Thanks, JKJ -- I'll look them up. CA lasts a long time in my hands; I store unopened bottles in the freezer for up to ~ 14 years with no problems (I warm them up to room temp before opening them), but clogged tips are another matter.
I put unopened bottles in the fridge with the caps on. I don't bother to let them come up to room temperature. The bottles last so long the plastic starts deteriorating before the glue is gone. I finally threw away one bottle I had since before I moved here to the farm in 2003; the tip was cracking and the glue was almost gone anyway.
I leave one bottle of thin glue out on the shelf with no cap. I do keep one of those tiny capillary tubes on it that let you put a tiny drop exactly where needed. Maybe that limits the moisture movement - this bottle has been open for over a year and is about 1/2 gone. Or maybe the humidity is just low in the shop with the AC in the summer.
The one medium thickness bottle I mentioned that the last 1/4 thickened up was the exception. I decided to try leaving it out in the room instead of returning it to the fridge. I don't think it lasted a year. Back to the fridge method for medium.
I have very little trouble with the glue clogging the tips. After use, I hold the bottle upright and squeeze to blow the remaining glue out of the tip. For the capillary tips I run a tiny wire through which cleans the sides. Eventually those capillary tips degrade so I stick a new one on the bottle. After I started using those tips I hate to use thin CA without one.
The Mercury CA bottles have a stainless steel pin in the cap that prevents clogging. They also claim to use plastic formulated to prevent moisture from permeating through from the outside, a problem with the plastic used for most CA glue bottles, according to them.
I think some CA glue is junk. I bought a bunch of cheap glue once and had all kinds of problems with it, including weak bonding. I save it for flooding punky wood.
I am not a big user of CA glue but am using Titebond. I keep them in a refrigerator and generally use them shortly after removing. I have had no problems with stopped up tips nor glue deteriorating. I tried some other brand whose name escapes me at the moment but was disappointed so returned to Titebond. Suits me to a T.

Have you heard something about this? They claim their glues are manufactured and bottled in the USA whatever that means. Somewhere I found a technical write up describing their R&D facilities but I can't find it just now and I'm headed out the door.
I do like their warranty:
"unconditional/unlimited guarantee on all newly purchased CA. If it hardens, we’ll replace it."
This is where I get mine and the price is right and the glue works just fine for me. As others do I keep it in the fridge when not using and have kept the large bottle with varying amounts for a couple years with no problems. I also order some extra bottles and the caps and use the large bottle for the refill, a good number of caps.
Ben, I think Wooden Wonders actually picked up the E-Z Bond line. I have been buying from E-Z Bond for years, as has my club. Compare prices. Example 16 oz. bottle you pay 28.33 and I pay 16.90 for exactly the same thing. Thats 11.43 difference. Its E-Zbond.com
