Works great
At first i used it with the nozzle but its hard to squish it out so I had to cut it from the second circle to make the hole bigger which worked, please do not force it through the smallest hole since Ive seen some comments complaining that it bursted open and made a mess. I would recommend you remove the nozzle when you are almost done and clean it properly by passing tissue through it, using some of that product leftover. While this might be messy and a bit wasteful it will prevent both the tube and the nozzle from drying up since the nozzle doesnt have a seal. Now i use it without without nozzle and it still works nice for areas that dont require precise application or tight areas and its an amazing adhesive, it says it dries in 1h but id recommend leaving it at least half a day, do the work at night and leave it overnight maybe. Ive used it to glue some shelfs in the kitchen and put spices and sauces which can be quite heavy, left milk and other heavy items to test the durability and its been 3 weeks holding all that weight, also used the glue to seal corners in the bathroom and its completely waterproof once dry. The next time u open the tube there will be a dried up crust on the top, if u squeeze a bit it should come out, i didnt throw it away and actually placed it back once im done using the product and this actually works as a second seal that prevents another dry crust. Overall amazing product.

Great Product-couldnt use 100%
Couldn't use 100 % of the material.started to used the product, kept the top plastic nozzle small (level 1-2), as to fill in smaller cavities.....the reason for my purchase.Somewhere midway of my job, not sure why, the tube punctured at the bottom, I guess due to pressure on top nozzle . later had to use my hands instead. Had to spent more time leaning it out.It was much easier to use the part flowing at the base, rather leaner way through the top nozzle.
