The phones come in two models: the NetLink e340 ($399), designed for office and light use, and the NetLink i640 ($599), engineered for rugged and harsh environments. The two phones are some of the smallest and most durable units we tested. Their industrial utilitarian design includes a four-line text display, and keypads sport a layout similar to a typical cell phone.

The i640 has a push-to-talk feature that allows an unlimited number of persons in one of eight groups to communicate, a service popularized by Nextel and useful in the vertical markets from which SpectraLink derives most of its income. The push-to-talk feature uses multicast to minimize network traffic. The i640 has been designed to withstand a 28-foot drop (we didn't verify the claim but did accidentally drop it on the lab floor once with no apparent damage) and comes with a one-year unconditional warranty. True to its industrial form, a multibay charger is available for the i640.

SpectraLink had sent us some gear a couple of months before we began formal testing, so we ran into a few glitches with older firmware versions. We were unable to power the phones back on after turning them off unless we removed the battery first.
