Stars
Reviews are pooled across the consolidated Amazon listing (B0D2ZWVNM2), which includes A1 Pro 300 lb, A1 Pro 230 lb, P1, and Z1 variants. The 1,630 count and 4.0 average reflect the combined product family, not the A1 Pro alone. 1-star at 14% (creeping from 11→13→14% over Feb-Apr 2026) and average slipped 4.1→4.0.
Max Speed
Amazon comparison table lists 0.5-3.75 mph, distinguishing the A1 Pro from the C2 (3.7 mph). WalkingPad.com tech params round to 3.7 mph.
Horsepower
The official spec sheet calls out a 1.25 HP brushless motor (WalkingPad). Amazon listing says 2 HP (peak, not continuous).
KingSmith lists the A1 Pro motor as 1.25HP brushless. WalkingPad/KingSmith HP figures are verified continuous ratings - the Z1 Pro Hybrid manual shows 550W rated power (0.74 CHP) matching its 0.75HP listing (KingSmith).

PREVIOUS ASIN: B0D7T4B7JQ (DFA 2024-07-24) - REMOVED from Amazon (404 as of 2026-02-12). This was a listing consolidation, not a discontinuation.
OLDER ASINS: B07SJCZLPQ (CCC tracked since Oct 2019), B08WTMLGXF (unverified) Model number: WPA1F PRO (Best Buy SKU 6560165, KingSmith product page)
Brand sites: WalkingPad.com: IN STOCK, $599 (300 lbs) / $499 (230 lbs). MSRP $799. KingSmith.com: OUT OF STOCK, $599 (from $699). Page still live. Best Buy SKU 6560165: Discontinued ("no longer available in new condition"). Rating 4.4/5 (11 reviews).
LIFECYCLE: Late lifecycle but NOT discontinued. Amazon flags the R3 (B0F8VP1CJ5, $659) as "a newer model." Best Buy has dropped it. KingSmith.com out of stock. Active sales continue on Amazon and WalkingPad.com. The R3 is not a direct upgrade - trades capacity (265 vs 300 lbs) for a wider belt (17.3" vs 16.5") and higher max speed (4 vs 3.75 mph).
KingSmith tech params: Motor: 1.25HP Brushless motor Speed Range: 0.5-3.75 MPH (Amazon comparison table; WalkingPad.com rounds to 3.7) Walking Area: 47"x16.5" (Amazon/brand description) / 47"x16" (KingSmith tech params) Weight Capacity: 300 lbs (primary) / 230 lbs (budget variant) Net Weight: 62-63 lbs Shock Absorption: EVA & PET App: KS Fit (with Apple Watch integration) Foldable: YES (180-degree fold, signature WalkingPad design) Voltage: 110V
CHP reasoning: KingSmith/WalkingPad HP figures are verified continuous ratings. Cross-verified via Z1 Pro Hybrid manual (WP400U4): 550W rated = 0.74 CHP matches 0.75HP listing. A1 Pro: 1.25HP listed = 1.25 CHP (trusted brand).
PRICE HISTORY: MSRP varies by storefront ($699 KingSmith, $799 WalkingPad.com). Street price is $599 everywhere as of 2026-02-16. Previous $549 sale no longer active. WalkingPad.com MSRP inflation from $699 to $799 suggests "permanent sale" pricing strategy.
INDEPENDENT RATING: Best Buy 4.4/5 (11 reviews, SKU 6560165). Product discontinued at Best Buy but rating still valid. 4.4 Best Buy vs 4.1 Amazon (pooled) - normal variation, not a red flag.
