They arrived today. Superficially they look fine but given this thread I had a closer look

Three boards and two showed a tool strike (or similar). Strangely, they were both around the same hole:


Then, of course, there are the nibbles on three sides where the boards have been de-paneled:

And a NPTH which is actually a PTH:

Doesn't matter to me in this project, but if you really needed NPTH that could be an issue. For reference, the JLCPCB NPTH:

Oh! Didn't I mention? The JLCPCB boards arrived today too, in the same post drop. So £5 for 5 or £17 for 3, same delivery time. Tricky. I can save another almost £2 with a VAT claim from Aisler, so that's really £5/board vs £1/board.
Both sets of boards were very similar, apart from the JLCPCB having no nibbles nor even any sign that there were any. Another thing, may be minor but could be useful, is how close to the board edge the ident can go. First, Aisler:

And JLCPCB, which gets much closer to the edge:

Another thing of note is that the JLCPCB via holes are smaller. One is also a bit off in that photo but both sets have spot-on holes and slightly-adrift holes.
