Back in 2004 I bought the two different sizes of Gluebots. I know they are dirt cheap in the US which is where I had to buy it from the total cost was A$38.00 delivered to my place in Perth. At the time I tried source them locally but no luck.
Over the weekend I had cause to use the glue (Aquadhere). Previous to this was about 18mths to 2 years ago. During this time when I would see the GluBot I would say to myself "I must check that bottle to see what the glue was doing" but never did. Anyway with having a requirement for the glue over the weekend I discovered that the glue in the GluBot had gone to gluk (was falling out like long strands of snot), nothing had congealed and I have been able to completly clean out the inside of the GluBot. I was very impressed with the GluBot
