Question: What is the noise level of the TC-10
Document: My wife and I bought the TC 10 and began a very dedicated workout schedule to lose weight and get in shape. The unit quit working in less than two months due to some electronic failure. In contacting for service the replacement parts were not available and it would be weeks before the unit could run again. We are very disappointed and Bowflex could only offer an apology for our lost time and effort.
I purchased a bowflex tc 10 in dec of 2011,primaraly for rehab purposes,for totalknee replacement& to loose weight. I first started out with a five minute workout which was all I could do. I gradually worked my way up to 3 to 5 work outs a week, for 40 to 60 minutes a time at full speed.
for the first few weeks I could only go for 10 minutes at 1 mph.Between Jan and Aug  I had 1 number to watch.. my weight. I went back to the doctor in August, the weight was 239... 34 pounds lost. I was a lot more nervous about the numbers I could not see and anxiously awaited his review of my blood work.
I've had my Treadclimber since February. I really like it for several reasons. I have bad knees and this machine allows me to get a great workout just by walking. It feels like you are walking up hill the whole time so it takes more energy to walk. I started out at about 1.5 miles/hour for 10 minutes 2x a day. As I got better at it, I increased my speed and also do 1 minute bursts at higher speeds.
I would definitely recommend this, it works wonders! It looks quite basic, but it gets the job done and you sweat like crazy! The only reason I gave it 4 stars instead of five is because the controls are very basic and for the price it would be nice to have pre-programmed workouts and a more detailed workout history in it. But those aren't really necessary just frilly! And it my husband complains that the cylinders make a lot of noise when you get past 3mph.
the machine felt kind of &#34;flimsy&#34; to me. i knew i would like the tc20 better but didn't want to shell out another grand. i happen to live a few miles from where they ship from and love the fact its a local co. but i packed it up and returned it,  saving me big bucks on shipping.
not bad for a 59 year old man with a plastic knee and a metal hip. thank you LORD GOD,and thank you bowflex.
i would have appreciated that offer at the beginning. i love doing steps and retired from a grain elevator and would often walk up 150 steps and then climb a 20 foot ladder which were attached to the outside of a silo. i wore a 40 pound weight vest while doing that. now retired i don't have access to those steps.
any machine is good if you use it, but to me it just wasnt worth it.
THEN, I received a $270.00 bill for assembly! There was nothing to assemble! The item had not even been shipped yet!!!! I called to cancel, was offered a $100.00 'bribe' for my frustration and was told I would be credited the assembly fee. I did not buy their offer. This company makes promises it cannot keep. They withhold shipping information and bill you for items you did not receive. NO BUSINESS ETHICS. Stay away from Bowflex.
