Question: The specs only mention an ipod port, does it have a regular aux input for mp3 players?
Document: I love having a way to run without being subjected to my area's terrible winter air quality and choking on it.The treadmill isn't super quiet, but it's an acceptable level of noise. The only thing I don't like is the noise level of the built-in fan. It does the job, and has two speed levels, but (especially the highest level) is pretty loud. I like having an "MP3 In" (3.5mm audio) port to plug my phone into.
Very happy with the high performance of this machine. Very smooth walker, rather quiet, easy to read display, programmable, and great incline. I selected this walker because of the name brand and the excellent warranty.
Very good product but very difficult to assemble. Also, the programed runs require you pay a monthly fee which I refuse to do. Also the machine is fairly loud making it had to watch TV while running
Upon opening the box, we realized that there were broken parts. None affected the actual use of the machine. You will want to take out all the parts to make sure that you have everything and that were are no damages. I learned from the first treadmill that you will want to make sure that the feet are secure and that you can stand on it without it wobbling.
This was a PAIN. It is very large & heavy, and I had to go up and down a flight of stairs to get it where it needed to be. The box nor treadmill have easy carrying handles or positions; it makes for a very awkward move. I ended up taking the main part of the treadmill out of the box and moved that separately, and this part definitely required help of a second person.
This is the first treadmill I have ever purchased. I spent at least a month researching them to figure out what would be best for me. The hard part about deciding is that the majority of treadmills in the sub-$1000 range are made by the same manufacturer, Icon, and rebranded to several different brands. Most notably, I'm sure you will see that exact same LCD screen across hundreds of different treadmills. So a lot of my comparison shopping was which rebranding is most appealing to me?
There are extra parts just FYI! *The space saver feature, well it doesn't really save a whole lot of space. It does incline up and latch, however it is not at a full 90 degrees. It still takes up quite a bit of space.If/once I hear from Reebok I will post an update. I gave it 3 stars because of the delivery, not the machine itself.Other than the delivery, the treadmill works great so far and I'm enjoying it.
The only issue I've had is the left hand pulse sensor doesn't work. The right hand one "works" though. I put that in quotes because the sensor seems pretty inaccurate, so if you really care about this feature, you'd be better served by buying a separate heart rate monitor. It will swing widely from 90bmp to 150bmp within seconds, which is not possible unless I'm about to die of heart problems (hopefully not the case).
The driver couldn't bring it downstairs on his own, so he asked if I could help. Obviously I said I would, and he told me which end of the box to grab. When I reached down to pick it up, it was EXTREMELY heavy. I had a hard time lifting it. That's when I noticed writing on the box right were I was lifting that said "This is the HEAVY end." No kidding!
That's it. He didn't offer to switch ends, or apologize, or anything.We did get it downstairs and my shirt and jeans were completely dirty with grime from the box. Fortunately it all came out in the wash, but it was an inconvenience. My arms got dirty with the grime too, and I had to scrub quite a bit in the shower to get it off.
Answer: yes
