Don't buy it, never received the product

For ESP-SparkBot AI LLM Desktop Robot Kit

I purchased the product, but it never arrived despite waiting a reasonable amount of time. I do not recommend buying from this seller, as my experience shows they are not reliable or trustworthy.

We sincerely apologize for the unpleasant shopping experience. We reviewed your issue immediately on Monday, our first business day. Because the lithium batteries for this product require special shipping channels, we've had other customers experience similar situations where packages were returned to our warehouse by the shipping company's agent and subsequently missed. We hadn't received your inquiry, and the shipping company we selected couldn't track the package in the Tindie system, causing the return to be delayed. We deeply apologize and have arranged for a reshipment. Due to the extended delay, we contacted you again via message and email to confirm if your shipping information had changed. Furthermore, the logistics company informed us that the situation in Chile is unique, and you now need to provide your tax number before they can accept the shipment. Once we receive your relevant information, we will ship it out immediately. If you haven't received it within a month, please feel free to contact us.

We included photos of the package we sent to the shipping company in our message and email, including the tracking number, date, and contents, to demonstrate that we did not intentionally delay or refuse to ship. We hope you can understand.

Great DIY kit

For 4Bit TD4 CPU Self-made 74 Series Chip CPU

I bought the DIY version of this 4-bit TD4 CPU, which requires only soldering the through-hole components and the 13 SMD chips. The LEDs, SMD capacitors, and SMD resistors have already been soldered with high quality saving a lot of work. The most challenging part to solder is the SN74HC540PWR SMD chip, which has a very fine pitch. The PCBs have clear printed markings indicating the correct chips and the position of pin 1. It also includes the instruction set that can be used. I'm using this kit to improve my SMD soldering skills and to have fun seeing the inner workings of a 4-bit CPU. There is a link to the technical documentation on github, which is mostly in Chinese, so it would be nice to have a downloadable document in English. Overall, i'm very happy with this kit!

I will let the GitHub doc has another English version soon. Thank you for your review
