Let me start by saying these mounting brackets are a game-changer for mini-split AC installations. I used them for my 12,000 BTU unit, and the heavy-duty galvanized steel construction immediately stood out - no flexing or wobbling even with the weight.

The installation was shockingly straightforward thanks to the foldable design and built-in gradienter. My husband (who usually hates DIY projects) had it up in under an hour. The rubber pads? Absolute genius - our unit runs noticeably quieter now with virtually no vibration transfer.

Two minor drawbacks: The foot slots are a tight fit (might be tricky with smaller 9K BTU units), and while the galvanized steel promises rust resistance, I'd still recommend checking the brackets annually if you live in humid climates.

Pro tip from personal experience: When installing, make sure there's no thread showing when tightening pipes to avoid system errors. And yes - they really do reply to customer service emails within 24 hours (I tested this!).

For the price, these brackets deliver exceptional value. They're sturdy enough for commercial use yet simple enough for DIY homeowners. After six months of use through storms and extreme heat, they still look and perform like new.
