Lifespan TR4000i Treadmill Review
treadmill Doctor Note :
This is not the best effort that Lifespan has ever put on the market. You are either better off in the upper or lower end of Lifespan's lineup.
This one is like the missing child in the Lifespan lineup. Great features, but you can get their full AC unit for only $300 more. Well worth paying the extra for the full AC unit.
The Lifespan TR4000i is not a unit we would recommend. At $1,699, you're only $300 away from the TR5000i, which offers much better quality, a better motor, and a better warranty. If you don't have the extra money, the TR3000i costs $200 less than this one and the difference in quality isn't that great.
The walking area is a good size. The belt measures in at 20" x 60", which has become the standard size walking belt on most of today's treadmills. This should provide plenty of room for larger users to run on comfortably without altering their stride.
A very powerful motor comes in this machine. There are several models that cost more than $3,000 that don't have the power producing capabilities of this one. You can reach speeds of up to 12 mph on this treadmill, so even experienced runners should have no problem challenging themselves.
You'll get a decent cushioning system with this model. An orthopedic belt and 8 variable density elastomers are used to reduce the impact that running has on your joints and back. Orthopedic belts can often be more hassle than they're worth, and you can find sub-$1,000 treadmills that use cushioning systems that are comparably durable and forgiving if you know where to look.
As far as projected reliability is concerned, this machine does pretty well. You'll usually have to spend an extra $400 to see an increase in the life expectancy, and even then, there's no guarantee. The quality of parts is also impressive in this price range.
The warranty on the Lifespan TR4000i is good. Labor is covered for 1 year, parts are covered for 5 years, and the motor and frame is covered for life. This is a very nice warranty for a reasonably affordable treadmill.
