If you already have a Dishmatic handle, I strongly suggest you consider this deal.
Dishmatic was the first to market in Australia and I was a big fan of the idea as it means I can wash with extremely hot water without burning myself (I don't like gloves). About 6 months ago, I tried the Chux model however I only got the handle as I had plenty of Dishmatic refills; Chux is "compatible" with Dishmatic refills. I say compatible in the same way the Australian Government says "free speech".
Now is the perfect time to switch dish handle ecosystems and load up on refills. I don't bother with the heavy duty refills as they can scratch teflon; use the non-scratch for everything. Don't bother with trying to use Dishmatic heads on the Chux handle, it will do your head in.
Chux heads have a better sponge, doesn't go a gross brown and is much finer so produces thicker foam, they also have a soft arrow head so they reach corners better and mold around cavities. They also manage dishwashing liquid flow FAR BETTER than Dishmatic which is key in handle features.
They don't often go on 1/2 price either.
