How it compares in Construction Machinery
Across the 26 rated construction machinery products we track, the typical score is 4.7 out of 5. This one sits at 4.2, which is in the bottom quarter of the category. That does not make it a bad buy, but there are better-rated alternatives on the same shelf, so it needs another reason to earn your money.
It carries 4 ratings against a category median of 13. That is a thin base by the standards of this category, so treat the score as provisional: a handful of extra reviews can still move it either way.
On price it sits in the lower third of a category running from £3.01 to £124, where the midpoint is about £6.97. Buying at the cheap end is fine when the rating holds up; check the specifics below rather than assuming the saving is free.
