I decided to try this product because it seemed to be a cost-effective alternative to its name brand equivalents. Well, the old maxim 'you get what you pay for' seems to apply here.The photos in the listing are MISLEADING in that they depict applicators that have black rubber tips on the head of the plunger that's inside each syringe applicator. However, the product that I received does not have the more-expensive black rubber tip design on the internal plunger but utilize a cheap plastic head instead.Why is this important?? I'm so glad you asked...As I've already mentioned (but it bears repeating), because of this variation in design, the net result is that the cheaper plastic heads on the tip of the internal plunger winds up having a much higher coefficient of friction than the designs that utilize the black rubber tips. Result: As a result of the increased coefficient of friction, the plastic heads stick to the inside walls of the syringe applicator making the movement of the plunger much stiffer and more difficult as a result. This, in turn, winds up requiring a lot more force to get the product to dispense and that in turn leads to waste.I do a lot of craft work and have excellent manual dexterity and hand strength. No matter how hard I tried to modulate the amount of force I used to dispense this product I would nevertheless always wind up with some waste and, as was the case most often - a lot of it at that. To give this product the benefit of the doubt, I thought that perhaps the first syringe was just an anomaly - i.e. that perhaps the first syringe out of the box was somehow defective or the victim of bad plastic casting. Nope - not the case: I'm now on my second syringe and can honestly report that this problem was not the result of a manufacturing anomaly - just bad (i.e. cheap) design. But perhaps what bothers me even more is the fact that the photos of the syringes for this product depict them as being of the more-expensive design that utilize the black rubber tip on the head of the internal plunger. This is a problem that I've found to be a bit too common for my taste with many products sold here on Amazon where the photos of the item do not accurately represent the item that one receives. There's an old-school term for this practice: FALSE ADVERTISING!My attached photos illustrate my point about the syringes:If you look at the photos I've included in this review you'll see three images: One of the syringe that contains this product (with a simple plastic head on the internal plunger), the second of an empty syringe that I purchased to use to dispense oral medication to my cat and, lastly, a side-by-side comparison of boh. Note that the syringe that I use for my cat has a black rubber internal "head" on the plunger and that it actually has two ribs to seal the product. Even with the double ribbing of the black rubber tip, it still takes far less force to get that medication flowing (and, for the record, the medication I give my cat is just as thick as the whitening gel that is this product). Now, this may seem like a trivial thing but to me it's not as I wound up wasting so much of the whitening gel because of the cheaper syringe design that they choose to use for this product. And, again, what I received is not the same as what is depicted in the photos!.BUT I DID FIGURE OUT A WORK AROUND:I gave this some though and I finally took a que from what I recall seeing many medical professionals due when they work with syringes. I decided to try PULLING back on the plunger a little FIRST to get it unstuck which I then found made it a little easier when I went to push on the plunger to dispense the product. So, if you buy this product... when you go to dispense it, first remove the small plastic cap that comes on the tip of each syringe, then pull back on the plunger a little first to get it unstuck and then, finally, push on the plunger to dispense the product. This workaround isn't a perfect and I'm sure there are other possible solutions but I found that this method works for me as does markedly lower the amount of the product that would be otherwise wasted if I didn't follow this procedure.I would have given this 4 starts instead of 3 had the photos in the listing been accurate - and 5 stars had the photos been accurate AND had they shipped me the product in the better-quality syringes as they claim to advertise. But as they are right now, the current photos that depict the applicators as having black rubber tips on the internal plunger and that's totally misleading as it isn't what I received.You get what you pay for (and sometimes not even that).I hope this helps.
