Hello everyone,
For a long time people have asked the question: are the 7 League Boots comparable to the Power skips?
In this review I will try to reveal the secrets and give an a direct comparison between the two products.
DeliveryLet’s begin with the delivery - it arrived neatly packaged and with a nice cover.
So to the unwrapping of the package. All important parts are covered with protective plastic sheet or even sewn in. This had its own problems as during unwrapping a seam got damaged -see picture below.
One further poor design was that the knee bow was on screwed at an angle .I had to open it anyway to adjust it for my body height but it still means that it has to be rearranged even if the height would have been ok.
A small but unimportant cosmetic fault I noticed was the label 7m is riveted too tight and started to splinter.
Design
Let’s take a look at the design and the most prominent appearance is the spring. The protection here is excellent and is far superior to that of the Power skip.
-> 7ms
-> PS
It’s nice to see a protective cover on the spring head. I have suggested this to many manufacturers and it seems someone at the 7 league boot company has listened.
What comes to your attention next is the frame; unlike other models the 7’s have square holes rather than round. As one can clearly see on the pictures the number of holes on the power skip is a lot higher which in turn makes it lighter, though possibly less sturdy than the 7 Leagues.
-> 7ms
-> PS
I’m always reading on the forums that the feet on the 7 Leagues are better than the competition. On closer inspection I can tell that is that the foot is defiantly thicker but I cannot see any difference on the profile between the feet on my fly jumper or the power riser. – All will be revealed on the practice run!
Something I have noticed only to be present on the power skips is a protective plastic plate above and below the spring protector.
-> 7ms
-> PS
Both the Power skips and the 7 Leagues have a substantial protective plate over the moving parts of the lower hinge.
The knee and foot bindings are identical apart from the colour so I will not go into any more detail here.
PracticeThe fist few steps on the 7’s are a bit wobbly as unfortunately knee bindings are not as good as on the power skips or similar models.
There is hope though, as apparently the 7 League Company is working on an upgrade to overcome that.
Once on the open road with the seven league boots, the first thing that goes through my head is, “damn they are quiet!” I’m so used to the loud clicking noise from my power skips; the noise coming from the 7’s is not even half as bad – thus more suitable for bouncing around on a quiet evening.
The foot bindings are not too reassuring. From a light jog to a sprint they feel ok and one can really move but when it comes to some serious jumping the grip does not give me a feeling of safety. I really am looking for some upgrades/improvement on that issue.
Now we come to the part of the report that will interest you the most - the spring! For the purpose of comparison I have got the T-rex (70-to 90 kg) verses power skip e520 (75-95kg).
Immediately there is a visual difference – The spring of the Poweriser/Flyjumper/Speedjumper is light green, the power skip a light yellow and the 7 Leagues are brown. (Observe in photos) The suggestion of the springs coming from the same factory as the power skips is hereby not confirmed. It looks more like a new development.
During the test is was difficult to see and feel the difference. I had to keep on changing the bouncers to make sure to get an accurate impression of the individual boots performance.
In the first discipline (jogging), both models came out well with no noticeable differences.On a sprint the 7’s were slightly better. At a certain speed the powerskip gives a lot of lift which makes it unpredictable for the inexperienced. This effect is absent on the 7 Leagues which on a prolonged sprint is more comfortable.
Discipline number 2: jumping on the spot. My analysis here is much like number one – both models seem to perform equally, each jump delivering more elevation. It feels pretty even with is confirmed by observers .
Even though the spring efficiency is pretty equal, the 7’s lose a point because of the previously mentioned bindings – not giving the sense of safety but once this has been ironed out they will be level pegging with the rest of them.
Next on the list is jumping off objects; in this case jumping off a table tennis table. Both products absorbed the jump pleasantly on an equal level. On the rebound one could tell the power skip is better, probably due to the difference on the spring performance - the extra 5 kg difference as stipulated in the Manual. Consequent jumps using only body weight without extra force applied showed a difference in height gain on the 7ms of about 5 to 10 centimetres.
SummaryIf the 7 Leagues make improvements on the knee holders and bindings they would be virtually equal to the power skips. As far as the springs are concerned and the protective cover; they are already perfect. For those of you who want to save money on the bouncy stilts, the 7 league boots are currently the better option; – at the moment there is a difference of about £300.
