What to know before buying

  • Compatibility is limited to suitable block-salt softeners. The listing says these blocks are not suitable for HarveyArc, Minimax Innova or TwinTec Cobalt, which use Mini Curve blocks. It also says one person may use one block per month, but consumption varies with water use.

Listing details to confirm

Listing details are inconsistent or unclear about weight: each block is described as 4kg, while the item-weight field says 4 kg and does not define its scope. The salt is described as sourced across Europe and shipped to UK manufacturing, while another feature says it is sourced from trusted suppliers and crafted in the UK. Confirm the selected listing's pack and origin details if these matter. The listed product weight is not a confirmed total shipment weight.

Who is it for?

A good fit for

  • Owners of compatible water softeners that specifically use standard block salt.
  • Buyers who want multiple blocks on hand and can store a 15-pack supply.

Less suited to

  • Owners of HarveyArc, Minimax Innova or TwinTec Cobalt models, which the listing says require Mini Curve blocks.
  • People whose softener uses salt tablets, granules or another format rather than standard blocks.

For buyers, the practical point is to check block fit and handle delivery carefully, especially because the listing specifies a particular format and excludes some models.
