Kiprun review

I like it but battery pack is Little heavy but you don't notice when u are wearing it. Strap falls off battery pack a lot. This is the main negative aspect.

So bright

Bought this light as the dark evenings arrived in 2020, as my run into and back from work 2 km of it is off road, so no street lights and pitch black, this light lights up about 20foot in front and it tilts down or up, brilliant light and still on the original batteries and still bright (jan2021)

Have used this several times now and can say it really works very well, brightness and angle options really good for lighting the way. Its also very easy to wear and I don't notice it when I am running at all.

Running torch

Brilliant, feel safer when out and about.

Super Value

Super Value Running Light whish is comfy to wear. Bright enough when off roading and fab in comparison to more expensive products.

Great light

So much better than the head torches - no one gets blinded & I can maintain a good upright from when running but still light up my route.

icon-circle-checkmark verified purchase

Bought this to replace my head torch which was giving me headaches on longer runs. The fit is secure but not restrictive; I am barely aware I’m wearing it. Nice bright light which can be angled down when running near roads so as not to dazzle drivers. Would highly recommend!

Amazing light from this. Comfy to wear

Not great for trail running

I find the beam is not bright enough, nor wide enough. The wide-to-side motion caused when running means that the narrow beam tends to almost exit your line of sight. It's really comfortable, but I didn't feel confident navigating technical sections of my run. Maybe okay for road running or easy gravel track, but not single track. I'll go back to my headlamp.

Za mě super používám na běh

Skvělá vychytávka

Koupila jsem to jako dárek manželovi na běh a také sama vyzkoušela. Oba jsme nadšení. Světlo je intenzivní, dobře drží aniž by omezovalo v pohybu. Co mi přijde velká výhoda oproti čelovce je, že jde světlo snadno jednou rukou naklánět podle sklonu terénu, takže máte stále velmi dobře osvícený prostor před sebou. Když potkám jiného běžce/chodce, světlo sklopím dolů, takže pořád vidím pod nohy, ale nikoho neoslňuji. Jediné nepatrné minus je, že kmitání rukou při běhu vytváří stín v kuželu světla. Rozhodně to ale nezhoršuje viditelnost. Doporučuji všem milovníkům běhu nebo chůze v noci.

Skvělá viditelnost

Doporučuji všem milovníkům běhu, kteří se nechtějí omezit ničím ani tmou.

Jsem maximálně spokojený. Jde štelovat velikost popruhu,krásně při běhu sedí na těle nikam nesjíždí. 2 režimy svícení,ale používám jen ten 1 před sebe vidím dobře. 2 zapínám pouze když proti mě jede auto a nechce vypnout dálková světla auto vždy rádo dálková světla vypne :-) Velmi rád toto světlo doporučím svítí pěkně.
