I have been using Appdrag for a bit and here are my thoughts:

On the "+" side:
1. It works very fast, delivers as advertised.
2. You'll need some coding knowledge in order to implement things, so it is not for the very beginner if you wish to have out-of-the-box forms, registrations, etc..
3. SSL included per each domain you use.
4. Their customer support is good. Not top and and not as quick, but it's ok.

On the "-" side:
1. Compared to other reputable and established Cloud Hosting companies, Appdrag will get expensive.
2. If you have a complex project, such as a website with subdomains, EACH subdomain will take one count out of your allotted sites per code. So a website with 4 subdomains will eat up one code. This is in my opinion counter-productive. ALL hosting providers allow 100, 300, unlimited subdomains to be built under a website. Appdrag calls it "apps" and each installation counts against your code limits. Beware, if you need a complex projects with departments, etc. (subdomain1.yourdomain, subdomain2.yourdomain..means TWO sites out of your limit per code). When I insisted to make sure that EVEN when I purchase a domain THOUGHT THEM this rule still applies, they said I am trying to trick them. I use multiple hosting services. Subdomains was never an issue. IMO, they shot themselves in the foot with this one.
3. I wish I had easy email access/implementation. For a client, they need to go through some loops to have everything under one roof.
4. Heavy limits on storage/bandwidth/number of sites compared with most if not ALL other hosting companies offering a similar combo of Builder+Hosting.

I am keeping one code for simpler projects maybe, but mostly for their builder. When other competitors offer unlimited Bandwidth on cloud, unlimited sites, etc...you will see that their annual plan after this offer expires is really not up to par. If you work with clients, do your numbers first.

Took out 2 tacos for the limits they have, and for actually being expensive in today's market (when stacking codes and then going annually.)
