I like that it's easy to use as well has all you need in one place! It is great how quick they respond if there are any issues or questions regarding your account/data etc., also their customer support team goes above & beyond what other companies do when answering our emails (it feels personal). As far an app customization? Not much available but still good so not many downsides here either except maybe some minor bugs which gets fixed quickly by them after we contact about those things via emailing us directly from within Lumas website itself - nothing major at this point though since everything works fine once set up properly anyways.. We have been able solve most problems right away through help@lumahqteam where everyone seems very helpful even during non business hours too whenever something pops out while using lumashare software / dashboard. This helps keep track easily of appointments made online alongwith.
