Too expencive if it is a "China-clone" (very likely as it states that SDS cannot be updated).
Because the most important thing is the software, not the hardware, as it has to be updated at regular intervals (new models).
This SDS "clone" do not support GSXS according to the specifications for this eBay item.
I would recommend Healtech OBD-tool.
I have had mine for many years, and the software is regulary updated.
It will also support other brands than Suzuki.
It is *the software* that matters!
