Review on 📶 Refurbished weBoost Home Room (472120R) Cell Phone Signal Booster Kit - Coverage up to 1,500 sq ft - All US Carriers Supported: Verizon, AT&T, T-Mobile, Sprint & More - 1-Year Manufacturer Warranty by Leo Torres

I have this at work and I use it for a hotspot or tethering with my laptop and I haven't even "aimed" the external antenna as I can't expose it outside (II Work in a factory or huge metal building surrounded by metal buildings). I usually had 1-2 bars but the data was sooo slow like using 2-3G again. Again I had to install an external antenna indoors but already under the ceiling and now I have 3 full bands but my signal gain was about 30-35dBm and about 40 points on the ace. The booster only gets 2 green lights where I am , but wow it's day and night compared to what it was. Worth the money, I've recommended it to almost everyone who has service issues. The brokerage platform I have installed on my laptop and use to trade stocks daily at work now works the same as it does at home. It was so bad that it was pointless to use it for a while until this thing showed up. I can't thank them enough for a product like this and it has helped so much.
