Overpriced. Highly Viscous . Not for beginners . But the best.
The media could not be loaded. We did 2 tanks with this . Nubies. Struggled with high viscosity . 1st tank leaked. 2 nd didn't . Not for 1st timmers. Sealed the tip , used it after 5 days to build another nano tank. With proper procedure , the tank leaked from all the sides. For one time use only. Bought it with extra shipping charges. Not worth the price. Not for nubies at least.And don't think this'll be usefull to professional . This glue just last for 30- 40 secs. Max before transforming into rubber. You can not do any changes in glass position after you put it on.Not for injection method too.Glue is strong i would say compared to other brands but comes with lots of cons.And self destruction starts after you cut it open. You can not use the leftover . Nope.Update after 5 months . Silicone is super strong. But requires expert hands to handle. Will be purchasing more .

Best silicon ever in the market, for aquarium.
Great product, dry instantly and very strong bond. My 400L aquarium seems pretty strong with this. Even you can't see any wobble of Glass when pulls or push like other silicon glues. But you need to carefully apply this one. Highly professional. I had used 2 bottle. After that i bought another astral brand silicon one from local shop, then only i realised about the quality of this wacker product, it's 100% greater than any other product in the market. The astral silicon i brought from the shop had a worst smell also it takes more than 24 hrs for dry. And also not having water holding capacity. But this one is great. Only cons i had was they don't sell smaller ones. If i need a 50ml or 100ml i have no choice for choosing this one. Because this product can't be stored for long after the seal broken.
