The app is inexpensive and starts at around $2 per user per month.

I think the pricing is fair and competitive and users would find that you might not have to break the bank to use the service. Also if you are inclined you can always make a local copy of your archives before and if you choose to cancel your subscription. Be careful though as with all subscription services the more you ask for, the higher the charges.

If you can afford it, go for it. I think the pricing is affordable.
