I bought this as a ladder for 25.98 offer. For comparison, I still have the Koordinationsleiter Anti-Skid 4M: ordered (ASIN B005W3HCWE, for 19.95 EUR). Materials and workmanship of the Reebok are not objectionable. Unfortunately, it is limited for me useful, as it has only five fields. So for a sufficient number of replicates per run you need at least two of those things. In addition, the sprouts are very smooth on the bottom, that is more suitable for use on the lawn as suitable for the gym (clear fix with tape goes, but is unnecessary expense). The spaces between the rungs are compared to other conductors relatively large - if you want to improve speed and accuracy, smaller distances are more favorable.
If you consider that you can not get far with a ladder, is the Reebok - despite Offer Price! - Relatively expensive. For the money's better.
