Disappointing experience with charging and support

I own a Flex 1500, which worked well when it charged, but recently it has completely stopped charging. I've attempted to contact the support team through email and phone for months without receiving any responses. My backup battery has now turned into a useless item. The emails indicate they’ve been seen, so why the lack of communication?

Disappointing Experience with Apex

We purchased the Apex in early 2020. It was mainly used as a UPS for my computer and taken camping for a total of six weeks since then. The on/off switch and disk failed. I reached out for repair, but they declined and had no parts available. Local shops couldn't help either. It feels like we have a $1000 anchor now.

Support Issues with Flex 1500

I own a Flex 1500. It worked well while charging, but recently it has completely stopped charging. I've attempted to contact support through email and phone for months without any response. My backup battery has turned into a useless item. The emails show they were read, so why am I not getting any replies?

Once Great, Now Lacking Support

I still have my original Kodiak, and it works well. This company used to be excellent with customer support, but five years later, it seems like no one is managing it anymore. A once-promising small company now appears to be struggling.

Delayed Flex 1500 Arrival

It took some time to receive the Flex 1500. At first, it was a decent unit sold with a 30-year warranty. I tried to get the locking switch replaced but couldn't get any help. It seems like they may have closed down. The timing with the pandemic and supply chain issues has affected many.

Warning for Potential Customers

Consider this a warning to potential customers. I ordered my Flex Tactical kit in November 2023, and it still hasn't been fulfilled. I've waited longer for this than for my home to be built. It appears they prioritize government contracts over public orders. I've been patient, but the lack of updates from customer service, which only responds after several days, is frustrating. My delivery date has been pushed multiple times, and I’m left wondering. I wish they would communicate better and not take on new customers until they can fulfill orders promptly.

Unfulfilled Battery Order

Our company ordered a battery in 2023, and we have yet to receive it. We've tried calling and emailing but have received no responses.

Product Works, But Company Struggles

I purchased a Flex 1500, and it performs as expected. Initially impressed, I ordered a second battery and the MPPT Supercharger, which took over a year to arrive. Both work fine, but I’m still waiting for my MC4 to EC8 cables. Customer service was good at first, but now there's no communication. They seem to have fallen behind compared to competitors. Update: I received the cables unexpectedly, but there was no explanation for the delay.

Positive Experience with Multiple Products

I own three products from this company, including the original Kodiak and the Flex 1500 with two batteries. The CEO even traveled to gather customer feedback. When the Tactical Flex was released, I purchased one as well. This has been one of the best companies I’ve interacted with. If I have questions, I can speak directly with their engineers. I don’t understand the negative reviews; my friends with similar products have had great experiences too.

Frustrating Purchase Experience

I echo others' sentiments. They claimed to have shipped my $3k+ unit, but the tracking shows it was returned to them. They then informed me it was 'stolen' but offered no recourse. I can't reach anyone by phone or email. This company has been a nightmare; please avoid them.
