I purchased AXA Shield when I first started out as an insurance agent with AXA 4-5 years ago.
Main reason I have gotten this Shield plan was because being the newest insurer, their premiums and coverage was VERY competitive (and it still is)!
Over my course with them, I got to experience the claims process for a handful of clients. Hospitalisation e-filing and post-hospitalisation claim was smooth and fast, almost hassle-free for both the clients and myself (the agent).
I moved on to join other FA firms and started dealing with Shield plans from other insurers too. Most of the time (depending on client's needs and wants), my clients still tend to favour AXA's benefit and cost compared to other the competitors.
I stopped dealing with AXA totally for almost 2 years now due to change of job. My Shield insurer remains the same.
(Reason why I rated 4 stars is due to my somewhat outdated experience. Otherwise, a 5)
