Best praise vs top criticism for ProForm Carbon TLX
“These two are good Options for $500 to $1000 **ProForm Carbon TLX;** All-New Treadmill for Walking and Running with Built-in Fan and Space-Saving Design **Hccsport Walking Treadmill with Auto Incline,** Air Cushioning Shock Absorption Foldable Treadmill for Home Office with Pulse Sensors, 10 Mph Speed 18.5'' Wide Belt Quiet Motor [If you want something Budget Friendly for Less than $500](https://goto.sycamorenet.com/REVO-Walking-Pad-Treadmill). This is a good light end running and walking Treadmill. Highly rated but remember its for lighter workouts. More heavy working. The previous two units should work well for you.”
“It felt small to me when I tested one of these. It’s the reason I didn’t buy it. Inspire (same company as Centr) also make a similar model (T5S) with a 15” display but that one costs $3500. The 15” one has a longer warranty, more powerful motor and maintenance free belt, but other than that is similar. Felt overpriced at $3500 so I went with the ProForm Carbon 9000 which had a 16” screen and cost about the same as the Centr Runr S.”
