These stores sell OBD2 scanners and full-system diagnostic tools directly, from $74.99 phone dongles to $600 tablets that run active tests and ECU coding. Sale prices at both are similar, so the real differences are the return terms, how fast the tool arrives and whether updates stay free.

How they compare (from each store's own site, October 27–28, 2026):

Store

Returns

Shipping

Updates

iCarsoft US

30 days, 15% restocking fee

Kingbolen

30 days, buyer pays return label

If you own one European brand, iCarsoft's single-brand V4.0 tools ($229.99 to $249.99) go deepest on that make. For a cheap bi-directional tool, Kingbolen's Ediag Elite was $74.99 when we checked.

Car Diagnostic Tools coupon questions

What is a bi-directional scan tool?

A bi-directional scanner can send commands to the car, not just read codes. It can run active tests, such as cycling a fan or an injector, and many also handle resets and adaptations. Kingbolen's Ediag Elite, K7 and K8 Pro and iCarsoft's CR Pro S and CR Max P are all bi-directional.

Do iCarsoft and Kingbolen charge for software updates?

Most of their scanners advertise lifetime free updates. The exceptions we found are iCarsoft's CR Ultra and CR Unicorn models, which use a $399 one-year update card, and Kingbolen's K10 Pro, which includes 2 years of updates and then costs $359 a year.

Which store is cheaper to return a scanner to?

iCarsoft charges a 15% restocking fee on non-defective returns and won't refund activated software. Kingbolen's refund policy doesn't list a restocking fee, but the cost of the return label comes out of your refund. Both give 30 days from delivery.

Are there Black Friday deals on OBD2 scanners yet?

Neither iCarsoft nor Kingbolen had announced a Black Friday sale on October 28, 2026, but both were already discounting their main scanners by 25% to 49%. Black Friday is November 27, 2026.

We put the two stores' main scanners side by side, with a price table and what a return really costs, in Kingbolen vs iCarsoft. Our Black Friday page shows which tool stores have announced holiday sales.

One tip for any scanner: check vehicle coverage by VIN before you order. Coverage varies by model year, and once software is activated, returns get harder or more expensive.
