I do not feel that that 1&1 offer good value for money. Their services are priced at a premium and do not live up to the company's brand promise.
My customer experience with 1&1 has been very poor. I'd rank it alongside that of low cost B2C service providers such as telcos, utility providers, etc. Access to support has been very slow, the company's systems are inadequate and I've found my dealings with 1&1 very frustrating. Little things like slow call pick ups, failure to transfer customer ID between colleagues and unresponsive IVRs grate after a while.
I've also found the services provided by 1&1 to be lacking. Three examples are:
1&1's hosted MS Outlook solution processes emails very slowly. We've often waited hours for an inbound email to show up in our inboxes. Many never arrive. No such issues with Google at Work apps.
Domain hosting is very restricted. There is no possibility for TXT and SPF verification unless taking a dedicated server package, so you'll have trouble with Office 365 and other email services that support sender verification. Microsoft actually recommend you transfer your domain to another provider if you don't get TXT and SPF support. http://office.microsoft.com/en-gb/office365-suite-help/create-dns-records-at-1and1-internet-for-office-365-HA103106443.aspx
I also used the company's CMS to quickly build a website for personal matters and also found this to be very restrictive in functionality compared with other solutions I have used.
