What we have not verified
We have not tested this machine. The figures below come from the official product pages we checked on 12 November 2026; confirm the exact configuration before you order.
Size and weight: not stated here. ComMarker's store page and its machine-comparison data give different dimensions and weights for the B4, so check the official product page. The Amazon listing we matched (ASIN B0BW8HWRBX, Brand ComMarker) is the 20W version; other power options are separate listings.
Size/weight conflict: store page copy says '270*380*560mm … 11 kg' while compare.js says 336×555×635 mm / 23 kg — both omitted.
Before you buy
- The exact version. Several of these machines are sold in more than one power or kit. The model name alone is not enough.
- The seller. Prefer a listing sold by the brand or Amazon, not an unknown third party.
- Warranty. Coverage belongs to the seller on your receipt. ComMarker's official product pages say “All products are covered by a warranty service.” The warranty period is not stated on the official pages we checked on November 12, 2026 (PST), so we don't state one. We haven't tested the products; confirm warranty terms with ComMarker or the seller before you buy.
