Sealey AK643
Price: £8.43 Size range: 65-110mm
The priciest three-legged product in this test, although it doesn’t bring any advantages over similar tools from Draper and Clarke. Even though it’s chunkier than our winner, in practice, that created clearance problems on tightly packaged filters. The legs required at least 10mm of space, while 18mm was needed above the filter for the top plate.
