The product was very easy to use.
However haven’t used the bike in anger since re installing the tyre asbit it had micro holes appear after cleaning the old sealant out.
The new sealant couldn’t seal them all.
New tyre is on order.
Will re review once done.

I've tried many sealants and I can say that this performs well under duress. Just had a massive 15-20mm sidewall cut that took 3x Dynaplugs side-by-side (finally used a big one!) which still didn't seal it, but with those and the Silca sealant, I managed to get the tyre back up to a rideable pressure and get me the the 25km to work with a couple of C02 top-ups along the way, and there was still sealant in the tyre when I took it off cos that size cut is never going to be repaired. I think that most other sealants would have just squirted out immediately. Probably ridden 5000km around Essex and into London with this sealant and that is maybe the third time I've had to stop to deal with a puncture. Usually I get home and see the tell-tale sealant specks on the seat tube that show I had a puncture that self-sealed without me noticing.

IMHO, the best sealant available. I recently changed my rear tire (mid August) which had been on since early February. Basically six months, and was amazed how much of the sealant was still liquid. EVERY other sealant I have tried over the years has dried out within three months. Silca Ultimate Tubeless Sealant is the ONLY sealant I will use.
