Have not had time to fully evaluate the performances of this unit. This questionnaire is way to early for a performance evaluation. Also, I have a question regarding the actual performance. The web site states the booster is 5G capable but all the documentation received states only 4G LTD capable. Is this correct?
Company Response
Joel: Thanks for giving us a fair review, even though you haven't evaluated the booster's performance yet. In answer to your question, the CEL-FI GO G32 will receive 5G from the tower and send it to your phone; if that's the case, your phone will display "5G" at the top of the screen. The GO G32 will transmit 4G/LTE back to the tower. This is a "hybrid" network. Since you'll typically uplink less data than you downlink, you can still take advantage of 5G downlink speeds from the tower. If you have any other questions, please don't hesitate to call us; we offer lifetime support on your system. 435-634-6800. — Powerful Signal

Shipping as overpriced, $15 to ship a $20 item with almost no weight is silly. Especially with ground rates. Feel kinda ripped off, but need the item for installation
Company Response
Ian: Thank you for leaving an honest review and expressing your dissatisfaction with our shipping costs. Unfortunately, shipping rates UPS and FedEx currently start around $15 for the smallest parcels. This has an oversized impact on orders for small items, like the one you placed with us. If you would like to cancel your order and find another reseller, please contact us before the end of the day and we’ll gladly refund your purchase! — Powerful Signal
