WORST PRODUCT EVER!!! DO NOT BUY!!!Firstly, you can not 'code' on all cars, it only works with SOME cars and worst of all, you WILL get STUNG with HIDDEN CHARGES and ANNUAL SUBSCRIPTION CHARGE! There is more chance in finding Elvis than a phone number for these clowns and any kind of any customer service IS NOT in their Ethos!!!*DO NOT BUY* DO NOT BUY* DO NOT BUY* *DO NOT BUY*
Scammers robbing useless diagnostic avoid avoid avoid. Company just a front to scam money. Won't refund subscription come with pathetic replies its just a scam keep the money you poor sad failing company
Essential features of the app simply do not work. In my case it was the battery registration function for a BMW. When the error was reported, Carly customer service admitted that this feature does not work and that a solution could take a year to appear. Since I purchased their app and scanner specifically for this function, I requested a full refund, but was offered only a 20%, then 30%, refund. I am currently pursuing legal and regulatory remedies against this company. Based on my experience, my advice would be to avoid dealing with this product and company.
This is clearly a scam for them to make money from a product that doesn't work at all. I bought a license for Audi and I tried to code the lights on my Audi A6 and it just keeps giving me an error and failing. I tried customer support to help me, and the response was simply that it didn't work and they couldn't do anything about it. It's a complete money-making scheme, and after I asked for a full or partial refund, they simply replied that no, it was my problem... It's a complete waste of money, money given to this company to grow in a shameful way... I do not recommend it at all.Translated with DeepL.com (free version)
Would give 0 starts if I could. Their scanner is practically useless, slower than slow - want to scan your car? You’ll be waiting 15 minutes. No it is not my scanner they have sent me multiple, no it is not my car I have tried on several. If you want to cancel your renewal then good luck they hide their shady business practices behind their “German rental law”
Where to start. Bought direct from mycarly. No mention of a reoccurring subscription. So paid what I thought was a one time fee. Scanner comes in and right off the start it was terrible. Took over 15 minutes to scan my car. Did not let customization like the say it does, had to look up everything it said was wrong. It is not very user friendly. Fast forward 12 months and I’m hit with a $110 charge. I was super confused and had to even look up what the company was since I wrote this scanner off as junk. It would be one thing to just be a bad product, but to have a hidden subscription that you have to cancel 30 days before renewal to avoid another charge is criminal. Junk product, junk service and a horrendous company. Buy any other one scanner.
The scanner malfunctioned and caused damage to my vehicle
Annual subscription for 115 euros for nothing. Carly does nothing more than free OBD scanners. And they don't remind you of the anniversary, they just charge the amount from your card... Thank You Carly!
Terrible company who rely on crude free scanner and expensive software that cannot be refunded even if you are not satisfied with product or it's incompatible with car. Horrible support that do not support at all. Far better, cheaper products on the market. AVOID AVOID AVOID
Horrible horrible
Refusal to refund auto renewal in violation of UK consumer law.
Scam, Scam, Scam. Avoid at all cost. Charging with hidden subscriptions and refuse to do any refunds. Charges your bank account without any notification or invoice. Avoid at any cost.
I am publicly warning people to stay away from this company. They will continue to renew your subscription at $165/year and make it difficult to cancel and impossible to receive a refund. They also DO NOT send renewal notices so be careful. Carly's subscription service is very predatory in their policies. A company worth anything would refund you if you forget about the auto renewal
Do NOT buy this! They bury the fact that it's an auto renewal for a yearly subscription (nearly 100 USD) and when it renews, they refuse to cancel. They don't even have a link on their website to customer service. You have to do a google search and open a ticket to cancel.Really, REALLY shady. Find a different OBD reader/ coder
Carly just throws up codes that aren't real. Every time it is plug in another list of false codes it's absolutely garbage the smart mechanic is Google it's so slow and a waste of money avoid at all cost.DO NOT BUY
you buy a licence, but its only for 1 year , scammy - the app is crap also
The product is awful. Very slow to loads and won’t clear anything. The app crashes and starts again complete waste of time
I was really disappointed with the Carly OBD scanner. The app is slow, laggy, and feels unfinished. It drains your phone battery quickly and frequently feels unstable - Avoid, main F%^%^ complaint is that all purchases of this device is a yearly subscription Plan ( Little warning / information on any of their websites nor to the Checkout page point to this fact, so every year Carly takes another £100+ out of your bank, extremely hard to maintain profile, nor any option to turn off Auto-Renew. Disgusting money grab practice, likely to be illegal.Again Avoid like the Plague.Overall, it’s overpriced for what it offers. There are much better OBD scanners available that are one-time purchases and don’t charge per car brand or lock basic features behind paywalls
Horrible. Money sucker. ZERO STAR
Following all the hype, I was interested to try one out and did not do my research before buying - a bad mistake. From initial plug in, it turned out to be unbelievably slow. It needed to update itself and do other admin trivia before it was ready to start, but then it took over 5 min with no indications of anything happening. After a total of 10 min, it showed signs of life and had detected the car and scanned the systems. But the App and device provide only very basic information. Free OBD apps that connect to cheap OBD plugins from China (TEMU for less than 5 Euro) are so much better. No, do not waste money on one of these - I have no idea why YouTubers continue to promote this. Additionally, Carly only sells a subscription, and that is really difficult to cancel so beware.
