[1] Typically, early adopters are customers who, in addition to using the vendor's product or technology, also provide considerable and candid feedback to help the vendor refine its future product releases, as well as the associated means of distribution, service, and support.
[citation needed] In exchange for being an early adopter, and thus being exposed to the problems, risks, and annoyances common to early-stage product testing and deployment, the "lighthouse customer" is sometimes given especially attentive vendor assistance and support, even to the point of having personnel at the customer's work site to assist with implementation.
The customer is sometimes given preferential pricing, terms, and conditions, although new technology is often very expensive, so the early adopter still often pays quite a lot.
[citation needed] The vendor, on the other hand, benefits from receiving early revenues, and also from a lighthouse customer's endorsement and assistance in further developing the product and its go-to-market mechanisms.
Furthermore, more efficient, and sometimes less expensive, versions of the product usually appear a few months after the initial release (Apple iPhone).
