Anyone used this? Worth bothering with?

Got a set of wheels where I’ve managed to knock the tension out of a couple of spokes, but they’re not too bad shape wise and they’re probably not worth paying the LBS rate on.

~£10 for true at most lbs how much would postage be on a set of wheels? About the same cost and more hassle IMO which is why they offer it for free as most won’t bother…

Sent mine off earlier in the year after the set i got from them went out of true after only 100 miles ! , sent them back for a re-true and they came back as bad as when i sent them ! … waste of postage in my view
Ill use a local shop from now on
