Doesn't standout from rest of the brand... Not buying it again ☹️
This silicon is really thick and High viscosity also little hard because glass need heavy force to traceout air gaps. It doesn't standout other aquarium silicon brand though it is mentioned 'aquarium silicon' .it's heavy mess because quality of silicon is such that it need too much beed and so much waste out of it, so more cost and moderate amount of beed leaves air gap. I will update on condition of silicon after a month strength might be good.
