I bought a wireless booster on 5 April, 2022 and discovered a few important points about mobile signal boosters in general and Boosters Direct in particular. A few cautionary points:
1) A signal booster will deliver the signal you recieve outside your premises/home to the interior, provided enough internal antennae are purchased, i. E. 2 bars outside converts to a maximum of 2 bars inside.
It will not boost the signal inside the home above what you receive outside. I. e. 2 bars outside cannot become 5 bars inside. So, if you can't get 5 bars outside you can't get 5 bars inside.
2) Boosters Direct may well try to upsell you to a cmore powerful/expensive booster, but this can not guarantee to impove the signal you receive outside. Check with an installer whether an external can be positioned to impove the signal you receive outside before you decide whether to buy a wireless booster.
