I have the Elite magnetic one from Halfords and while it is adequate, now that I realise I use it more than I thought, I wish I had invested in a better one. Tis a bit noisy, but I can live with that. Also pretty well made so no complaints there. However, the level of adjustment (5 levels) seem pretty close to one another. I realise running only a 35/12 front/rear combo doesn’t help, but it is certainly nowhere near enough resistance to stand up in the pedals and if I want to get HR to max out I have to bounce my knees off my chin at a cadence of about 130 in top gear and top resistance.
