Bondic Liquid Plastic Welder Refill Cartridge 4GC003

I'm a fan of the system, but I wonder if this refill is fresh. I recall the liquid in my original kit being colorless when new, though it became more amber over time and eventually lost its ability to cure hard. Though the refill was sealed and presumably new, the liquid is already yellow. It seems to work, but I question if I'll get a year out of it....

This product works so well and I am so glad I found the refill!

I just got this delivered and it is not only just the refill (unlike imaged), but not a buy 1 get 1 free deal. What a JOKE for $14.97. Not Happy.
