I went the 'cheap Chinese' route (because I hope that it will be a temporary fix while I get my main speedo to work with wonderful accuracy in spite of the cable currently being incompatible with the Type 9 5 spd box 🙂) .... my Defender has a spot-on accurate mechanical speedo (measured against various GPS and roadside speed warnings) ... so I tested it out by fitting it in the landy ... was surprisingly accurate and except for taking 30 secs to 'boot up' initially seems remarkably stable here in the NE Scotland.

Having an idea what revs correspond to what speeds as a temporary fallback for if you do get a drop-out might be reassuring.... though I guess in your case you can temporarily forgo the HUD in favour of the main speedo if that happens

I believe TBM has used one in his Morgan for some time, so maybe he can give us a 'long term test' report?
