I just bought the upgraded version of the Sleek, from the Weboost company, aka Wilson. It runs on 12v.
It kinda works. I see no increase in bars on 4g on the signal strength, but I do get somewhat of a better page loading speed. I've been buying stuff like this for years. Even fashioned a 15' long pole to hoist up on the roof. I just haven't found anything that really works that's worth bragging about.
Are you using it with one of the bigger antenna's like the trucker antenna? All the bigger antennas give you additional gain for all bands except the one T-Mobile uses for much of their 4G, in fact they claim a signal loss of about -4db for that band. The little stubby antenna that comes in the box with the Sleek is the only antenna they sell that claims any real gain on the T-Mobile 4G band. Also if you are using it close to a cell tower you will likely not see any improvement either.
