Great Deal For the Money!
Loctite is counting on their name as the original, but they are getting way too expensive. This huge bottle from Pro Seal will last me for years! I've used Pro Seal before, and it works just as well as Loctite, for a fraction of the price. I can barely buy a little tube of Loctite for the price of this huge container. It's slightly smaller than a squeeze bottle of Elmer's Glue! I'll definitely be back for more

Extra! Extra! Read all about it! Bargain threadlock adhesive saves small businesses!
I own a flight case manufacturing business and we used to go through lot of the 3M blue thread lock adhesive, mostly on caster wheel bolts. I always got mad when we had to order it because I just knew it was overpriced but we didn't seem to have any choice. Then I discovered this product about two years ago during an Amazon search and although skeptical because of the huge difference in price, I decided to try it. It turned out to be a very good gamble. The feedback has been that it works just as well as the 3M product and I can tell you it is about a fourth or fifth of the price. If you have a production operation you really need to try this. Call it a small victory for a small company. Don't tell O and his cronies though, that'll be good enough reason to put an excise tax on it! Like uh....... oh yeah, cheap gasoline!!

1/4 the price for the same quality as that other brand
So much cheaper than the Loctite brand but works just as well. I fill up smaller dispenser bottles with it and them store them in the refrigerator to extend the shelf life, share some with friends, etc.. My go to brand now and I use a lot of it.

Good product, good value
Great product. HUGE bottle for the price. Forget those 6ml tubes for $6, this has more than 8x the product. I found the tube a little hard to work with, when I needed to get product into a tight spot. I had to drip some on a paper plate and apply with finger in a latex glove. If the nozzle isn't below the horizontal plane you can't really get anything out of it. Squeezing just produces air. Note, it dries fast once in threads but remains in liquid form when exposed to air. Overall very good. No more price gouging from Loctite on this.

Great threadlock at a fraction of the price.
Huge bottle, works as good as any other thread lock. The cap is very well made and seals bottle. I used to buy Permatex or Loctite but there is no reason to pay the same price for 1/10 th of the product.

viscosity of the content is too liquify
it did not work since viscosity is not suitable to stick to where it supposed to be applied and discoloration occur.
