Just received a brand new, DEFECTIVE Magnum 357 plus LED light

Like the title said.

Anyone ever dealt with this company for customer service? I'm seriously thinking of packing that lemon right away and sending it back and demand a refund. One screw wasn't even actually screwed on the case. It was just in there and fell when I took the thing out of the box. It can't be screwed back on either, the hole is too big.

What do you guys think? Do I even try to get this thing to work or should I just send it back and demand a refund?

Any ideas, suggestions, recommendations?

EDIT: after searching a lot, I realized this has happened to other people. Apparently, the power supplies can be knocked loose during transportation. The box I received was pretty banged up and even had a boot mark on it (DHL is the worst shipping company in the world, they handled the box like it was trash).

I talked to Dave from GrowPerfect, he sent me two replacement power supplies (I just need one) the same day. They should get here within a week.

I'll update when I receive them.

Update: after a month of veg, my plants are at a whopping 3.5 inches tall. Perfectly healthy, but they don't fucking grow. Absolutely no signs of deficiency or toxicity. Perfect and uniform green color.

This lamp will bleach my plants at 3 feet above the canopy at full spectrum. It's been at 4 feet above the plants for 2 weeks. 4 FEET. THAT'S RIDICULOUS. Every Monday I try to lower it to 36 inches, tips start to turn white within two hours. I switched to full spectrum after two weeks of blue only and absolutely zero growth (1 tiny set of true leaves in two weeks).

I have a 6 foot tall tent. I need 3.5 feet of distance and the top of my pots is 10 inches. That leaves me with 20 inches of possible height. Even with a Scrog, maybe I'll get a god damn ounce out of 4 plants if I'm lucky. I'm starting to think the grow journals I saw using the mag+ were complete fabrications. There is not a single variable that is problematic except this lamp.

Canna coco, preflushed, 3 gallon Smart Pots, precleaned.

Reverse Osmosis water at 5.8, no variance, 22 degrees Celsius.

Biggest temperature variance during the day: 0.5 degree Celsius, climate controlled room. Day/night temp DIF: 5 degrees Celsius.

Biggest humidity variance during the day: 5%.

Using Botanicare Pure Blend Pro Grow (5 ml/gal) and Liquid Karma (2 ml/gal), and GH's CaliMagic (2 ml/gal). Ridiculously low, I know. But that's because they're still the size of 2 week old plants and show no signs of needing any more.

I've never had such perfect growing conditions in 10 years. I use to grow with excessive heat and big variances throughout the day. The same strain (dr greenthumb's Bubba OG), is usually about 12-15 inches tall at this time (with a shitty old 250 watt MH that costs 50 $).
