Pros
- Cheapest real heat/cool machine on this page — the 16K-gal HEX055 runs about $1,999 (currently $1,899 with a coupon), Amazon-direct with a working cart, and it genuinely reverses to chill
- Buy your exact pool size: the same inverter listing scales from 3,000 to 26,000 gallons ($599–~$2,899), so you're not over- or under-sizing
- The best-proven pick here: 4.4 stars across 510 reviews on the listing, a deeper owner base than the name brands here carry
Cons
- Import brand with a shorter US track record and a thinner dealer/service network than Raypak or Hayward — factor in support risk
- Aquastrong states a 55,000-BTU heating figure but no separate cooling BTU, so its exact chill rate is unproven on paper — buy it for the value and the owner base, not a spec-sheet pull-down
- The 16K-gal HEX055 is small-pool sizing; for a bigger pool step up a size in the listing, or to the top-discharge HEX075TOP if your pad needs discharge routed up
