I bought a bottle of IC2000 but it went off very quickly and won't ever buy again.

I spent substantial amount myself on this IC2000 by BSI also and I had the same thing with the entire bottle going off (hard) in the bottle even with the original manufacturers lid.. not at all happy about the wasted money and will not and can not recommend this rubbish product. I even emailed BSI about this and have never heard back from BSI about this, typical for such a business to simple take my money for inferior products.

Avoid BSI products at all costs...
