The caps of the tubes seem hard to remove or to replace compared to other brands. Fighting with the caps on a glue stick shouldn't be a concern but the glue quality itself is fine for everyday use.
I use the glue sticks primarily for sealing envelopes. They work better than messy sponges or water. However I don't find them that strong. Once the glue dries it's easy enough to open the envelopes or anything else the glue stick was used for.
