The perpetually "coming soon" Maximum Signal Max-Amp was on our radar for over a year before finally being certified by the FCC for sale in May 2015, and Maximum Signal began taking pre-orders shortly after.
For a while we were beginning to doubt the Max-Amp would ever make it to market, but at last in April 2016 the hurdles seem to all have been crossed and the first handful of production units of the Max-Amp RV finally shipped to customers.
The slightly less powerful (less interior coverage claimed) Max-Amp Mobile was released shortly after - shipping in July 2016.
With bold claims like "minimal antenna separation" and "easily covers a 53 foot RV" - we had high hopes that the Max-Amp would prove to be a worthy competitor to weBoost's product line.

Alternative Versions
There are three similar variants of the Max-Amp.
The Max-Amp RV is designed for large RV installations, and the somewhat cheaper Max-Amp Mobile is designed for vehicles and smaller RVs. They also make a Max-Amp Truck and Trailer Package with two antennas - one for the RV and one for a tow vehicle.
News, Videos & Status
We initially received a Max-Amp Mobile from Maximum Signal in July 2016, and it did not perform well. Maximum Signal sent us a replacement unit, which did not arrive in time to be fully included in our late 2016 booster testing round.
Because there has been so much interest in this booster, we carried it forward into our new Early 2017 testing round - putting it head-to head against the new HiBoost, Smoothtalker, and the tried & true weBoost Drive 4G-X.

Maximum Signal primarily sells direct, though they have begun to sign up a few official dealers - one of which occasionally offers products via Amazon.
Cellular boosters can be quite useful for boosting the signal to a smartphone to get a more solid phone call. But when it comes to enhancing cellular data performance, things get more complicated.
Because of a technology called MIMO (multiple in multiple out) that is essential to LTE and 5G data, often times the internal antennas on a smartphone or hotspot don't benefit from an amplified signal. Boosters also only cover a handful of the frequency bands the carries use for data.
But a booster can play a role in a mobile internet arsenal - as they excel during times when you are really far from a tower, or where upload speeds are important (such as video broadcasting).
