Poor experience with NOCO 10 Genius and NOCO Support
Purchased a NOCO Genius 10 3 years ago. Only used it a few times and it stopped working. Tried to call NOCO Support but the number on the NOCO website went through to an individual who said he gets lots of calls from NOCO customers but has nothing to do with NOCO. Sent NOCO Support an email. They never responded. Very expensive piece of kit which was very poor quality and NOCO support appears not to exist.

GBX defective - junk.
Bought a very expensive NOCO GBX45 jump started and only used it twice. The unit will no longer accept a charge which appears to be a common problem. I have messaged their support team and await a response when I will update. Update - no response from customer service. I saw advice to try the cigarette lighter charger lead when the unit no longer accepts a mains charge. I bought a NOCO brand charger but still can’t charge the unit. So my view is this very expensive item works only twice then becomes another piece of landfill junk :-/

Bought a GB50 several years ago
Bought a GB50 several years ago. Very expensive. Stopped working. It will charge (I think) but then immediately turns off. Only used 2-3 times in total. Spoke w/ NOCO, they won't refund (out of warranty), or even try to repair. I did a teardown, the switches in the GB50 seem to have failed. These are ultra-cheap switches, no idea why NOCO puts such cheap switches in a $130+ product.

They promised a certain product but…
They promised a certain product but sent a different product and it didn't have all the components. And their customer service is horrific! Do NOT buy from them.

Great customer service
My Genius 10 stopped working after a little over a year. I emailed customer service wondering if replacement would be a possibility. They were very quick to respond. There were other reviews on here saying they make you "jump through hoops", which I believe is incorrect. Yes, you have to provide serial number and proof of purchase. They also want to see a picture showing that you have cut the cables. I see nothing wrong with asking these things with all of the scammers in the world these days.I easily provided them with what they needed, and my replacement is on its way. Kevin at customer service was quick, friendly, and provided a great solution to my problem. I would highly recommend.

Great boost packs customer service sucks!
Great boost packs, own two. Customer service sucks. No number to call, only chat and email options! Can’t get a straight answer on when the charger I ordered will come! I ordered directly from Noco. Has been 3 weeks… Update: after multiple vague emails from noco I was finally given estimated delivery date and charger for boost pack did come. Funny thing is there is was customer service number on the receipt… why not on website?

Absolutely rubbish charger
Bought a Noco Genius 10 from Halfords in the UK, specifically because it could charge 6V batteries. Couldn't get it to charge anything, neither 12V or 6V. When switched on, it cycles through the charging stages until it goes green in about 15 minutes, as if it's charged the battery but clearly hasn't. Took it back to Halfords who replaced it - new unit does exactly the same. Fortunately my trust old Ctek unit comes to the rescue and charges the 12V batteries the Noco can't. Still can't charge 6V batteries. Owned 2 Noco chargers and never managed to charge one 12V battery after umpteen attempts between them. Avoid like the plague.
