I bought a couple of those.... but the tube clogs up really fast and I was good at replacing the cap etc... By the time I used the product a second time, I couldn't get the main tube to open and had to try to force a needle down it, which made an absolute mess trying to hold the flexible body... I had to actually rip off the top to get any glue... so for me it was good for only a couple applications before it became unusable...
I like BRS bottle and now only buy from them....
