Yes we have one at home- Horizen is the brand and we got it at Dicks sporting goods.I have said to my DH you usually buy a piece of equipment and then wish you went with a different model or just aren't happy with it.I have to say I love ours and it has not become a clothes rack.We have had it for a few years now.
Much better on your knees than almost anything but swimming,Overall excellent workout because you use upper body as well ,opposed to the bike.
The key is to gradually increase the time and intensity of your workouts and the weight will come off, as long as a nutritionally sound diet is in place as well.
Good luck,
Linda
