  Crystal Quest Thunder 1000C RO

  • Crystal Quest recommends but does not include a leak detector valve, and says so plainly, which is more candour than most under-sink RO sellers offer.
• Ease of InstallationAquasure Premier Pro 100 GPD: 6 (higher)Crystal Quest Thunder 1000C RO: 5

  Aquasure Premier Pro 100 GPD

  • The LED faucet is a convenience rather than a measurement: it counts time or volume rather than testing water quality, and it does not replace a TDS meter.

• Contaminant ReductionAquasure Premier Pro 100 GPD: 8Crystal Quest Thunder 1000C RO: 8

  Aquasure Premier Pro 100 GPD

  • A larger membrane refills the three gallon tank faster after it is drawn down, which is the practical complaint people have about tank RO systems in households that drink a lot of water or fill pots from the tap.

  Crystal Quest Thunder 1000C RO

  • The 3.2 gallon stainless pressurised tank is a real upgrade over the steel-and-bladder tanks typical at 300 dollars, and the membrane is swappable up to 100 GPD with arsenic, nitrate and fluoride cartridges available for the same body.
  • The stainless faucet option was listed as unavailable.
• Certification CoverageAquasure Premier Pro 100 GPD: 2Crystal Quest Thunder 1000C RO: 2

  Aquasure Premier Pro 100 GPD

  • Certification is identical to the rest of the Premier range, which is to say Aquasure's only NSF listing covers two membrane part numbers for material and structural integrity and nothing on this system is certified for contaminant reduction.

  Crystal Quest Thunder 1000C RO

  • There is no NSF/ANSI 58 listing, so the twelve-stage architecture is verifiable from the parts list and the performance is not.
• Flow RateAquasure Premier Pro 100 GPD: 5Crystal Quest Thunder 1000C RO: 5

  Aquasure Premier Pro 100 GPD

  • The drain ratio stays at 1.5 to 1, so the extra output does not come at the cost of wasted water, which is the trade some manufacturers make at this capacity.

  • Product-line.
  • Two r/WaterTreatment and r/HomeMaintenance threads cover the Premier RO platform.
  • One owner reports 420 ppm TDS at the faucet on a new install, settling to about 360, which is a poor rejection figure and the more relevant of the two for a system sold on membrane capacity; the second describes the Flowlok leak-detection disc deploying during a filter change when a drain-line fitting leaked.
  • Nothing addresses the 100 GPD membrane or the LED faucet specifically.

  • Two r/WaterTreatment threads are titled directly on Crystal Quest RO systems.
  • One draws an installer replying that the system is good and that they have fitted several; the other is a buyer who has heard the brand recommended and is stuck between roughly twelve models and seven optional add-ons, which is the clearest statement anywhere of what the configurator costs a shopper.
  • An r/sandiego thread recommends the under-sink RO from years of use.
  • Neither is long-term ownership reporting on this model.

  • One analysis names APEC, iSpring, AquaTru and Brondell as the direct comparisons that do hold finished-product NSF/ANSI 58 listings for TDS reduction, which is the cross-shop this system loses on paper.

  • IrixGuy's Adventure Channel, 98,800 subscribers, has two independent owner reviews of the Premier RO - one after several months at 6,100 views and a several-years follow-up - and a separate third-party self-install walkthrough covers the same 4-stage system.
  • None names a specific capacity, so this is the Premier line rather than this model.
  • The pump configuration is not addressed separately, and the RO roundups that bench-test at this price point do not include Aquasure.
  • Brand-level coverage is the Harmony softeners: DIY Homestead Projects at roughly 115,000 views, NKP Home Improvement at roughly 94,000, geminidrums at 15,000 on the fine mesh and IrixGuy's two-year owner review at 13,000.

  • The independent channel that lab-tests reverse osmosis systems included the Crystal Quest Countertop Thunder in a 26-system countertop comparison but not this under-sink model, so the testing that exists on the Thunder name does not reach this chassis.

  • Product.
  • The Premier Pro 100 GPD reads 4.2 of 5 from 16 ratings on ASIN B07FKCM6T2 - a real pool just above the ten-review floor, and the lowest product-level Amazon figure on any Aquasure system.
  • It sits two tenths below the softener line the rest of this brand's Amazon evidence rests on, which is worth saying wherever that figure is used.

  • Brand-level.
  • The Thunder is listed on Amazon as ASIN B00A2C1Y92 with model options 1000 through 4000 and returns no rating, so there is no product figure.
  • The fallback is the Amazon brand-insights panel, which reads 4.3 from over a thousand ratings with 5,000-plus orders in the trailing three months and prints 4.2 on a minority of listings.
  • The closest hardware on the platform with a real pool is the countertop reverse osmosis unit at 2.4 from 36 — the same technology at a smaller scale and roughly two stars below the panel — which is why the brand figure is scored well down here rather than taken as a proxy.

  • Home Depot reads 4.2 of 5 from 10 reviews on this exact system.
  • That is exactly the ten-review floor, so the figure is scorable but should be read as the thinnest usable pool in this brand's set, and the 75 GPD Premier Advanced at 4.5 from 41 is the better-evidenced point of comparison on the same platform.
  • Both pools are native, with verified-purchase entries and Aquasure replying under its own support address.
  • Across the three Premier configurations Home Depot holds, the ordering runs 4.5, 4.2 and 4.0, which puts this in the middle on a count too small to make that ordering mean much.

  • Trustpilot reads 4.0 from 54 reviews with 37 in the past twelve months, bimodal at 50 percent five-star against 39 percent one-star, with under-sink reports on both sides: a pinhole leak in a canister answered with a free replacement the next day, and an eight-year-old system still leaking after all six o-rings were replaced.
  • BBB Kennesaw is the disagreeing second profile at 1 out of 5 from six customer reviews against an A plus accreditation, and one BBB complaint concerns a Crystal Quest RO system that failed at two weeks.
