Yesterday had a leaking bicycle tire, still holding the air for about 20 minutes. The coat was from the outside without damage, so I guessed only once a leaky valve. After exchange for a new tire but lost still gently but surely the air. So I thought it is an opportunity the time Nigrin breakdown spray test. I had never really believed in the efficacy yes, but who has not tried it, I thought .... Well, the tires pumped up by the gas in the bottle really hard on and also the foam seemed at first to exert its effect, but unfortunately, already 2 km of air pressure began to subside noticeably again, because I was still 15km away from home. So if now 100000 customers buy this spray to test it first time, it has probably definitely its purpose (for the producer) met. I would recommend it under any circumstances and and say: people, remains the venerable repair kit. Although this is more complicated (and therefore, the manufacturer of this spray well on the sales success) but in the time successful. Stay away from these promises on fast and above all effortless sealing the bicycle hose! Actually, I wanted to give no stars, but here must forgive one because I can give the review without a single star here is not.
