My five star rating is mainly for the customer service I received. I liked the result of the product, but the salesman at the store in Maui,HI used every overbearing sales tactic in the book. When I said I was going to leave as I wanted to see Maui, not spend the day in his store, he gave me an offer I finally took. He went in the back room and brought out a “damaged” box of the Instant Repair Syringe. Since I would be taking a cross-country flight home in seven days, I decided to wait until I got home before opening the syringe as I didn’t want to chance any leakage in my luggage. Once I got home and tried it, I pumped the syringe until my hand tired out and not a single drop came out. My receipt had “Final Sale” stamped on it and I figured I had been scammed and I should have trusted my instincts about the salesman. I came to this site as I wanted to let them know how their product was being used for this scam. Ilan responded promptly and explained an issue they had with production. Once I sent the requested proof, a replacement syringe was sent to me. Unfortunately that one appeared to have the same problem so a second replacement was shipped and that one works! I don’t see why they just don’t put the product in a squeezable tube instead of the fancy syringe! Anyway, customer service is top notch!
