My experience with Wilson/WeBoost is interesting. I wanted a booster for home, we have -105db signal and I was hoping to get some improvement. Emailed to confirm details and right selection, response was my environment should work very well with abc (don't recall exact model) booster. I was ready to purchase and had one more question, so emailed again. Got a response that my signal was too weak to be boosted... I responded that I was told previously (attached previous email to my response) that it would work well. Engineers had it out, WeBoost decision was my signal would not benefit from their products.
I am not planning on buying anything now until I see what happens with 5G.
