Bought this a month ago now, saw good reviews but was nervous buying. All nerves were put to rest once it arrived. This is a really solid sturdy treadmill that feels of great quality that gets used for both running and incline walks by both me and my partner. Very happy with my purchase, I just know it will last a long time
We bought the treadmill 3 weeks ago. It turned up ahead of time. The delivery and installation process was excellent and could not be faulted. Well worth the extra to have it installed. Very happy with the treadmill. The treadmill itself has easy to understand/use buttons for speed, incline and program selection. There are a couple of APPS we can also use, however have not downloaded yet as we will use the treadmill as is initially.
I bought this after my apex was a bit under sized for me (couldnt handle my weight) so it was exchanged for this model...... Very sturdy frame... programs are silly dont waste you time with them.... the warm up program default speed is like 2 kms an hour? You change it but it doesnt scale the rest of the blocks so you adjust the speed to say 4 kms then hits the next block in program and it will dip back to 2kms..... cant adjust the the program ahead before use....... has to be while its going...... the arm rests are a cheap feeling plastic..... but all in all its a sturdy treadmill good for walks on an incline can handle my weight (115kgs) so if you just set the speed and incline and start walking or running its good... if you wanted a dynamic run well your gonna be disappointed
My wife and I bought this a few weeks ago. It is absolutely perfect for what we need. The design philosophy of this unit is very clear- It is about providing a powerful motor, great walking bed, good ergonomics and the basic user interface to make it plug and play, with additions such as integration with the FitLink app, means you can control the treadmill completely from the app. It is a no frills treadmill, but if you're a heavier person trying to lose weight- this is perfect. I weighed 119 kgs (when I started using this), my wife was 136 kgs. It hasn't struggled at all with our weight. This I feel is important to declare in a review because in the past I've followed weight ranges on treadmills only to discover later that the reality didn't match those advertisements. The M4 is also very, very quiet. You can have a conversation while walking, watch TV, it doesn't dominate the room. My one critique is that when walking on it, it can shimmy a bit under foot, so you'll notice your phone wobbling while walking. It's probably just my weight and it will probably be less noticeable as I lose more. I found when reading for reviews that basically none existed so I thought I'd write this to help others. No regrets. PS. I'm waiting to find out if the lifespan wireless heart rate monitor integrates with this unit, Ill update this review when I find out.

Purchased the RTM Wall Mounted Pull Up Bar from Cardio Online. Compact, easy to install product with great functionality. Rated up to 150kgs, I'm only 80kgs and the quality feels all good - but would probably not put much more than 100 - 110kgs onto the bar. Good grip padding and ideal for a home gym. Would recommend it :)
It is a great product
I am using it for 4 days now as I received it last Saturday
It helps me to be active
It's been 3 days and everything is good so far. Shipping is good too.
Shipping was brilliant. The gentleman was wonderful and very helpful in getting it off. My husband assembled it, and everything worked and looked great.
It’s good so far. I’ve been using it for three days now and it’s fitting well into my routine.
