They're cheap (especially if you agree to share a van) and were fine. And even though they're called manvanlondon they're more quite-a-few-men-with-some-proper-trucks.
Not sure I'd use them to transport Ming Dynasty vases, but they were fine for a basic move. Hope this helps.
We used Alexanders - for moving only, not packing. They were very good. Turned up on time, happy to wait whilst the house paperwork was sorted, and managed not to break anything.
