Great Glue
I've been using BSI glues for years. Both as glue and as coating for my turned wood pens. Works great every time. If you use the accelerator with these glues they may become brittle and the glue joint could break easily. For a good long lasting joint, don't use the accelerator.

Super expensive for glue, but the best
I want to start out saying this is the glue my company nation wide uses, it's top line stuff. I bought it for use outside of work and learned how expensive it is, but I suppose the best will be expensive. Warning to those who decide to buy some though, this stuff has a super strong chemical fume and can burn your nose, throat and eye balls. So just be cautious on how much you use at once. If you need to use a lot, at least wear a respirator mask. This stuff dries quickly to. If it gets on your skin it can burn a little. Oddly enough if you use paper towels to wipe it the paper towel will smoke. It's interesting. Adheres to metal, wood and glass very well! Great product for professionals!

great CA
Great glue. I keep it in the freezer between refilling my bench 2 oz bottles. Keeps it fresh and safe. refill bottle has a good spout on it to refill smaller bottles. Been doing it like this for the last 30 years.

A must have for every home, shop, business
This is one of those products that once you have discovered the millions of uses in just your own world.... The only time you might be disappointed is when you realize how much the was wasted without it. This product along with the Bob Smith accelerator primer.... the liquid to make it cure instantly and increase adhesion with almost every type of material under the sun is just a must-have for every home I mean you can fix so many things instantly it's just going to blow your mind. you want to get some cheap latex gloves to wear while you're using for quick cleanup but by it also you might want to buy some small disposable little 1 oz bottles that you can use for actually dispensing the glue and just use this big bottle for refilling that way your big bottle doesn't get all souped up and crusty on top

Cheapest way to buy the BEST superglue on the market!
I use a lot of superglue on many projects, so I buy this 8 oz size to refill my smaller bottles. Reduces the cost by about 60% or more. I keep this refill bottle in the fridge to extend it's shelf life. Having trouble with clogged superglue nozzles? Soak them in acetone for a day, it cleans them right out. I keep several old nozzles soaking in a glass jar with Acetone all the time (with a lid on it to prevent evaporation and spilling) and when a nozzle I'm using clogs, I just get a cleaned one out of the glass jar and drop the clogged one back into the jar. Some of them have soaked in there for months, and it doesn't affect the plastic the nozzles are made from.

Versatile Glue
This medium viscosity CA glue is my go-to glue for so many things. I am a woodworker, and use it for lots of stuff around the shop. Things like making my own double-stick tape (with blue painter’s tape) and the quick glue-up of joints that won’t get a lot of stress on them. I sometimes even use it in combination with wood glue as a kind of clamp to hold things in place while the wood glue dries.

BSI is our go to CA adhesive. It just works!
We have tried many different CA's over the decades but none stand the test of time like BSI adhesives. Some of our clients have models of their product models and trade show models in their lobbies, C Suites, and government offices. I have yet to receive that call stating that a glue joint failed. Even the trade show models that travel several times a year hold tough. If you want a little bit of resilience in something like a plaster model, try their IC2000 rubber impregnated CA. We use a lot of that adhesive too. Their debonder works incredibly fast and easy. Just remember to have paper towels at the ready in case you spill.
