Rating: ⭐⭐⭐☆☆ (3.5/5) Price: £3.50 - £5.00 (estimated) Verdict: Does the job, but only for the right job.

Only if Sainsbury’s is the only shop open at 10pm on a Sunday. Otherwise, spend £10 more for a proper bellows-style or flange plunger online.

If you buy this, go to the hardware aisle and spend an extra £1 on a rubber flange attachment (if they sell it). Without it, you are just pushing water sideways. For the price of a sandwich, it’s better to have it and not need it than need it and not have it.

Anyone with a modern, elongated toilet or a household with toddlers (who flush toys). For that, you need a flange plunger or an auger.
