The base is excellent.
Sturdy, heavy, enough to keep the tablet perfectly stable and secure.
Even in an upright position (portrait), the tablet (10.4') remains stable, without giving you even for a moment the feeling that it might flip over.
A base that truly deserves its money.

After almost 1.5 years of hosting a 10" tablet and enduring rough treatment from a kid, it remains in excellent condition, being durable and with the joints still tight.
