Ah OK - 500m isn’t terribly inspiring but let’s hope you see an improvement.
Mine appear to be lost. Royal Mail say they have never entered their network, and the tracking provided stops at Heathrow. In fact 4PX seem to have reused an old tracking number which shows it was delivered on 04/12/20 - then shipped on 08/05/21… Which may have caused some confusion somewhere along the line.
I’m in the process of ordering a couple more, and a couple of batteries from China too. Just in case the first ones ever do show up I’ll have four working units.
The seller has put the price up since I ordered the first ones…
