Proform 840 Treadmill
The Proform 840 treadmill has been discontinued by the manufacturer and replaced.
See my recommendation for a treadmilll in this price range by following this link to best treadmills.
If you were here looking for a review of this model because you’re buying a used machine from either Craigslist or Ebay, I DID recommend this model when it was still being manufactured by Proform – only buy one if there is very minimal wear and it’s newer than 2 years old – and never pay more than 1/3 of the original retail price, period.
