I've used the product before so I knew ahead what to expect from the product. Shipping was prompt. Product has not been changed, same great epoxy. You cannot beat the convenience of the one use little bubble packs. Each use is fresh, full potency epoxy. Once you open twin tube type epoxys, they slowly loose potency and ability to harden. And often you find they leak. Unless you have a big volume job, double bubble is the way to go.
