Customer Reviews
Got my OBD2 scanner fast
Ordered an OBD2 scanner from DiagMart last week. It arrived pretty quick, like 4 days to my place in Ohio. The scanner works as it should, hooked it up to my truck and cleared a code no problem. It was easy to find what I needed on their site. No fuss, no drama, just got the job done. Good experience overall.
Reliable for software updates
This is my third purchase from DiagMart, mainly for software update cards and some accessories like screen protectors. They're consistently reliable. My Autel MaxiSys MS906BT updates seamlessly with their cards. Shipping is always on time, usually within a week. I keep coming back because I know I'll get genuine products and solid service without any hassle. It's comforting to have a go-to place for my diagnostic tool needs.
Absolutely amazing scanner!
Oh my gosh, I just received my Autel MaxiCOM MK808 from DiagMart and it's incredible! The shipping was so fast, got it in like 3 days to Texas. Setting it up was a breeze, and it's already helped me diagnose a tricky issue with my car. I can't believe how powerful this tool is for the price. I'm definitely shopping here again for all my diagnostic needs and telling all my gearhead friends about it!
Good value on Launch X431
I was looking for a good deal on the Launch X431 V+ and found DiagMart had a professional scanner sale going on. I picked it up for a solid price, felt like a good saving compared to other sites. Shipping was free which is always a plus. The scanner itself works great. Overall, I feel like I got good value for my money and the purchase felt worthwhile.
Quick delivery, good product
Ordered a TPMS diagnostic tool. Arrived in 5 days. Product was as described. Works fine. Satisfied.
Decent experience, minor shipping delay
I bought an Autel MaxiCheck MX808 from DiagMart. The price was competitive, especially with a professional mechanic discount I managed to use. The scanner itself is genuine and works perfectly, exactly what I expected from Autel. My only minor gripe was shipping; it took 7 days to reach Denver, which felt a bit longer than I anticipated. Customer service was helpful when I inquired about the tracking, though. Overall, a positive experience, but slightly quicker shipping would make it perfect.

hey, trying to figure out if these autel scanners are actually legit from DiagMart. seen some sketchy sites selling fakes before.
can i actually get technical help for setting up my scanner after buying it, or am i on my own?
do the scanners from DiagMart come with the global software versions, or are they region-locked?
any professional mechanic discounts available? or like, a student discount?
i signed up for their newsletter, but didn't see any first order discount email. is that something they usually do?
