The product is fantastic for the intended role, but the technical support/documentation is lacking or requires a lot of search (e.g. flashing ready-made firmware you need to source in some hidden forums or you need to program it yourself - the offficial sources say you can use the standard t-echo firmware, but that doesn't work. Also the new option with the whip antenna is solved by via 3 connectors/reductions before the antenna so not ideal for the reception quality)
