As simple as it is, it's still a very valuable and useful tool when diagnosing issues with one's builds! Plug and Play. The shipping was extra fast as the seller is local so cannot judge how fast it travels longer distances but it was shipped the very next day after purchase.
The LED debugger works perfectly and as expected. The shipping took a long time and I thought it wasn't coming. I contacted the seller and it was shipped, and sure enough it arrived. It works well and I am glad I bought it.
