How it compares in Components & Replacement Parts
Across the 44 rated components & replacement parts products we track, the typical score is 4.6 out of 5. This one sits at 4.8, which puts it in the upper quarter of the category rather than level with it. Where almost everything is rated well, the gap at the top is small in points and large in practice.
It carries 211 ratings against a category median of 2,596. 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 middle third of a category running from £4.99 to £625, where the midpoint is about £39.99. That is the part of the range where most sensible buys sit, neither cutting corners nor paying for the name.
