Mich had asked an Amazon customer for a comparison (see my Hudora-review). If you do not have both auspobiert itself to a comparison, however, can only be limited to technical data, and to what is manifestly light on photos. Here is my comparison:
The Hudora is (on Amazon) is currently slightly more expensive (30 euros), it has a slightly higher mass (7 instead of 5 kg).
In addition, the front Hudora has two small floor rolls to him so simple to scroll through the apartment (rather than to carry or scrape on the floor).
He has on the operating panel three separate keys, instead of just a single rocker switch with three Wipprichtungen.
Hudora (German company from Remscheid) has a certain brand Bonus, including long-term supply of spare parts, and normal company telephone number (so no 01805er call center rip off as the Ultra Sport).
In the Ultra Sports Photo with the muscle man (enlarged view) I imagine, forward already to discover on the plastic body three dents? If so, this would be an indication that the body of the Ultra Sports Plastic is not very robust, and over time could become unsightly due to scratches?
Ultra Sport obviously saves on Cent amounts, in any case, the plastic cover was on the tube bottom to save.
Apart from these little things I can think of no differences. Whether I would have all together 30 Euro difference value? subjectively probably yes (for a better feel), I also find the floor rolls forward useful. If that matter is, but the course can save 30 euros, because of the training effect is in both (hopefully) equally well;) And hitting +2 kg flywheel makes the Hudora probably only a little nuance more pleasant.
