    Quick and painless

    Needed a signing certificate for filing documents and this was straightforward to obtain. The certificate details match our registered particulars exactly. Better price than the certificate authority charges directly, for the identical product.

    Worth it

    Filed our returns with this signature and the portal accepted it first time. The token arrived quickly and was ready to use.

    Did what I needed

    Ordered this for e-tendering and the registration went through without a rejection. Renewal was simpler than the first issue, as expected. Recommended if you want this done without a fuss.

    Painless renewal

    Used this for signed PDFs that our clients need to verify. Works as described. Support stayed on the call until the signature appeared correctly. No complaints at all. Straightforward transaction.
