Overall Summary
Scam
  Why we think so? 

This eBay listing offers a "TI-84 Plus Calculator" described as featuring internet access for ChatGPT, Gemini, and DeepSeek, which standard TI-84 calculators do not natively support. The seller, "tr_566122", has a 100% feedback score but only 2 reviews, which is far too few to prove a reliable track record. The seller does not accept returns, which increases risk to buyers. Price is $239.99, much higher than legitimate, unmodified TI-84 Plus calculators, which typically cost $100–$150. No legitimate retailers offer a commercial TI-84 Plus with built-in internet or AI features—examples found online are DIY hacks, not official products. There is no evidence this is an authentic, supported device, and the feedback volume is too low to rule out manipulation or inauthentic reviews. Combine these points, and the risk of scam or counterfeit is very high. 🛑

Detailed Checks & Insights

0-100 Scale

Does the product listing describe a plausible product or service based on known brand history and product features?

Score: 50
Failed

"Claims to provide ChatGPT and Gemini on a calculator, which Texas Instruments does not make or support."

Reason: No authentic TI-84 Plus calculator comes with internet or AI integrations; standard models are not capable of these advertised features.

Does the seller have an established, trustworthy sales history, with substantial positive feedback over time?

Score: 10
Failed

"Scam sellers often show perfect feedback with very little history. The 100% rating here is statistically insignificant."

Reason: Feedback is only 2 positive reviews; this is not enough to establish trust or reliability.

Do the seller’s item descriptions, photos, and terms (returns, shipping, guarantee) match those of authentic, established sellers?

Score: 20
Failed

"No mention of warranty, authenticity guarantee, and seller refuses returns."

Reason: No returns accepted, which stands out as a major red flag for high-value electronics. The item description is also vague, with implausible claims.

Is the price consistent with what similar, authentic products cost from major retailers?

Score: 10
Failed

"A huge price markup with no clear explanation is a strong risk factor."

Reason: The price ($239.99) is much higher than authentic TI-84 Plus calculators which sell for $100–$150, even new. There’s no evidence the modifications are genuine (or possible).

Are there any direct complaints or scam warnings about the seller or listing on respected external sources?

Score: 20
Failed

"Absence of negative reviews is not evidence of safety when other risk signals are so strong."

Reason: No external scam complaints were found specific to this seller, but the combination of implausible product, zero past sales, no returns, and high price brings serious risk.

Does the fulfillment pattern and logistics (location, shipping method, payment, receipt) match typical authentic sellers?

Score: 15
Failed

"A physical USA location suggests legitimacy, but does not outweigh the listing's implausible technical claims and lack of returns."

Reason: Seller location listed as Chicago and normal payment methods shown, but shipping promises and logistics aren't enough to offset the many severe risk factors.

Your Next Steps

  • 1

    Do not purchase this item. The combination of implausible features, high price, very low seller feedback, and lack of returns policy strongly indicates a scam or counterfeit.

  • 2

    Buy Texas Instruments calculators only from major, authorized retailers like Amazon.com, Walmart, or the official Texas Instruments store.

  • 3

    Check the eBay Money Back Guarantee coverage, but be aware that not all listings or scenarios are covered—when feedback is very low, consider it a red flag.

  • 4

    Report suspicious listings to eBay for further investigation.
