The Wellgo and One23 RO-96B are effectively brothers.
As mentioned already, they share exactly the same casting and, come to mention it, cleat.
However, the visual is only skin-deep, and you soon notice that the downside to the £12 price difference is finish and bearing quality. That said, they are lighter (286g).
Although the finish may not be quite as high-quality as the other pedals on test - noticeable in the pedalling action - for the price, this could be a good starter set if you are still unsure about getting started with clipless pedals.
