Pros
- Wirecutter's top pick for sheer heat output (February 2026); CNN Underscored and others recur on the HLDS01 family
- Open tank door — swap the cylinder without lifting the housing
- AZ Patio Heaters publishes real clearance figures and sells its anti-tilt switch as a serviceable part
- Wirecutter: 'Like AZ/Hiland, East Oak provides reliable customer support'
Cons
- The Amazon base is stale and thin — the visible reviews run 2012 to 2021, nothing since, and 11% are one-star
- One-year warranty that excludes 'damage or repairs related to insects, birds, or animals' and 'rust or weather damage' — the two ways these actually die
- Stock was single-digit at the read ('Only 7 left'); AZ disclaims the warranty on non-authorized sellers
- A flimsy base that bends, and start-up trouble, in the critical tail
It arrives bent — 'Everything was bent, and damaged. Rivets where broken on the latch' (Jan 2022), 'both are dented and damaged. One of them is missing the latch' (Nov 2021), 'Damaged on delivery, second delivered was damaged as well' (Nov 2021). Second theme: ignition and the tank connector — 'trouble starting this every time… this weekend, September 2022, I took it to the dump', 'the connector to a propane tank doesn't work'. Third: three-plus-hour assembly.

Pro review “If you're simply looking for sheer heat output, get the AZ Patio Heaters HLDS01-W-xx, also sold as the Hiland HLDS01-W-xx.”— Thom Dunn, Wirecutter (The New York Times)
