x-jet vs turbo injector

[tmc]

i'm looking at buying either the "x-jet", or the "turbo injector" by Water Research USA. does anyone have experience with either of these products?

The x-jet can be useful for some things, but down streaming is far more efficient.

Ditto on the down-streaming. More efficient and more cost effective through less chemical wastage.
