I bought this to replace a previous cross-trainer that had broken and would have cost too much to repair (which seems ridiculous in today's world when we need to conserve as much as possible - boo to Nordic Track). Anyway, I was very pleased with my purchase of the Viavito Sina Elliptical Cross Trainer. It came in several parts as shown in the photo, well packed in a strong cardboard box. It took around an hour to assemble with clear instructions from the manual. The fact that all the washers, nuts, bolts etc. were sealed into a clearly labelled blister pack was very helpful. I have been using it daily for just over three weeks now, with a 45 minute user program, and so far I'm very happy with the quietness of the machine (but see below) and its performance. It seems very robustly constructed, but time will tell whether it holds up to regular use over time. Some pros and cons: (1) The computer unit is very clear to read and I like that it's bright and uses two colours (blue and white). (2) There are several built in exercise programs, but I love that you can program in and save your own program (which I have done). (3) The read out, during exercise, gives you a time count down, speed and RPM, distance travelled (estimate), heart rate (if you have a monitor belt or use the grips), and watts. (4) It features a heart rate monitor as noted (which many others do) but this one measures your recovery rate and rates it on a 6 point scale. (5) You can also store individual user profiles with gender, age and weight, and it gives you your BMI and body fat score. (6) When putting it together, there are three possible locations for the footpads, about 5cms apart, so you can choose to set it up to suit your posture. On the not-so-good side: (1) It does tend to wobble a bit (and yes I have made sure the feet are properly levelled, and it sits on a thick wooden board for stability). I think this is probably true of all cross trainers because of course as you use the machine your weight is alternating from one side to the other. My concern is whether it is robust enough to last - my last two machines both broke due to this issue, i.e. wear and tear on the machine where it is fitted on to the legs. (2) It also has a distinct squeak on one side when I first step on to the machine (though this goes away when used "in anger") and I will dis-assemble the relevant parts and re-grease; but they were well greased originally, so it's a bit of a concern. (3) Finally, it has no place to put a tablet so that you can watch a video (or whatever) while you exercise. I have rigged up something that works for me, but you'd think this would be factored in in modern cross trainers. All in all, very happy so far; just a little concerned at how long it will last under constant use.
