About Plain Buy Guides

Plain Buy Guides is an independent site owned and edited by Isaac Daniels. It isn’t owned by, paid by or partnered with any brand it writes about, and Amazon has no say in what it writes.

  • Guides use manufacturer specifications, manuals and warranty terms to compare fit, included parts and setup needs.
  • A capacity or runtime stated by a maker is labeled as the maker’s claim, not a Plain Buy Guides measurement.
  • These are research-based guides; they do not claim hands-on tests. Check the exact model and package before you order.
