Hello , received my exchanged items today the cost including VAT works out at just over £230, so considering that each item is £170 is it worth it, well only just. I think as time goes on the LV101 and LH90 will devalue so perhaps. I feel I didn't save that much. Also LV101 cannot act as a booster and it could damage your units, the old LV100 had jumpers you could set for it to be a booster so beware. I asked Lenz technical. Thanks for all your comments and advice but it all ended well. Take care and thanks.
