Well that's just a
very crude Bulli knock-off. And the Bulli's have a jumbo juice cart (no cart on Nhaler's, drip only).
Sizewise it's just a tad larger than a DSE 801.
With shipping from Germany it's only a few dollars more than Nhalers @ $75, but it comes with enough wire/fiber for 10-12 replacement coils.
After that though, if you've bought some spare wire/fiber (5M of each) you'll be making replacement assemblies for less that 30¢.
Having the coil accessible also makes cleaning it so much easier as now you can lightly brush off some of the crud.
Do note these will take a little experimentation and fiddling at first to 'get it right', but the long term benefits are worth it.
