Does not work!  Continuously leaks from nozzle.

After attaching this product to a 2 liter of pop, the nozzle continuously dripped, until the 2 liter of pop was almost empty.  Not happy about this at all. Definitely would not purchase this again.  I saw this and was so excited, that I purchased 4 of them, to save on s/h.  Never again. Good idea, if it actually would work properly.

This faucet was purchased for a remodel, so naturally it was a few weeks before we even opened the box.  It leans, both the faucet and the hand sprayer leak for MINUTES after turning them off, and today, five days after installation, the faucet has turned itself off entirely and I can only get water thru the hand sprayer.  It is awful. We even replaced the washers with no luck or improvement.  Of course, since the remodeling dictated when the box got opened and the faucet got tested, I am outside the 'return' window, and cannot contact the seller!  I am anxious to see how Amazon responds to my experience. This will seriously damage my reliance on Amazon.

My reviews are usually positive, and I don't recall ever according a product one star. But I feel it's richly deserved here. It arrived in a timely fashion, and sprayed without issue two or three times. And then the nozzle simply would not spray anymore, no matter what I tried. I wasn't even done spraying one shoe that I was trying to stretch. I shook the bottle, and rotated the nozzle multiple times, but no liquid will spray from the can, even though the bottle is full. Bitter experience. Given all the other positive reviews, I must have received a defective unit. I will not be returning it; too much of a hassle. I'll just order a different brand.

This adapter is leaking at a swivel, meaning its not user error, this adapter cannot hold the water pressure! Do not buy!

The unit was fairly easy to install, but the nozzle portion is cheap.  The water pressure drops next to nothing, unless I hit the bottom several times and then the pressure goes to about half line pressure.  It's just barely usable.  I'm trying to find a replacement nozzle, but no luck.  It's horrible that I would have to replace the entire unit and waste the over $100 I spent on this.  It's not fair.  I'll continue to try to contact the selling company for the part, but eventually, I'm just going to have to throw it away.  That pisses me off.

Doesn't work...water just leaks out & nothing sprays from where its supposed to. My son had it on ONE time & hasn't used it since.

This is a totally worthless solenoid valve. The 3/4" threads on each side are not tapered, (not National Pipe Thread) so you cannot stop this thing from leaking. I tried Teflon tape, JB weld and epoxy and cannot stop it from leaking 30 PSI water. Unfortunately, I bought two of these. Lesson learned!

Used less than an hour and it won't work! Pressure build up in hose made trigger inoperable so no water could pass through

This is garbage. I bought this pump thinking it would be perfect to have in my bike bag after forgetting to air up at home one time before riding.
Today was my first chance to use it and the nozzle stuck. This released nearly all the remaining air from the tire.  (and yes, I realize that this nozzle latch operates the opposite of how most are configured) I was able to get the schrader valve connected to the pump but it would not create pressure. I wish I had just bought a good one instead of trying to save a few bucks. Perfect example of the old saying "buy it expensive once, or by it cheap several times."

I flipped through the positive reviews to see what people really do like about it. Based on what's written, I suspect that people wrote these reviews because they were so happy they bought something so small and compact, and its sitting in their bag in case it's needed.... but they never tried to use the thing yet.

I bought this at Home Deopt.  It was faulty or defective.  It was professionally installed due to getting hew laundry sink.  I will have to remove it and install another.  If there were zero stars I would give it zero.  I like the fact that it has the sprayer attached, or the idea.  It is, however where the supply line is clamped to the sprayer head that it leaks when the water is turned on.  Spend more and get a quality product.

Avoid this product! It arrived quickly and undamaged (thanks Amazon Prime!) but the hose leaked so much at the nozzle hookup that it never held enough water to expand. I couldn't tell you if it would ever grow to a 100' length or not. Also, the product description said it was compatible with all normal water faucets and hose accessories--it is NOT. There was no way to attach it to my sprinkler. Completely useless product--returned it the same day.

garbage. didn't work out of the box! something is jammed or mis cast in the sprayer nozzle end. not more than a slow dribble no matter what setting/water pressure. hose connections feel flimsy.

I have purchased two " Viking 912600 8-way heavy Duty spray nozzles" and there is nothing heavy duty about it. It leaks when I rotate to a different spray pattern, When I squeeze the trigger it sprays and does not stop when releasing trigger.  The second one that I purchased does exactly the same. This lot of this product must be defective. i will not purchase this product from this vendor/ manaufacter.

Tried painting a room, The sprayer wouldn't work!  So I diluted the paint 50% with water.  This time a trickle came out of the nozzle.  The next step was to place the sprayer very carefully in the trash and use a brush with my now runny, water-downed paint!

Got this 2 pack yesterday 04/24/2018. Today opened one up and installed its black spray nozzle. Shook the oontents up and used it to spray a little on my pants legs, shoes and socks.  Put the bottle aside for about an hour and came back to use it again but the spray nozzle trigger broke and quit spraying! Cheap piece of junk nozzle.  They put a notice in the packaging saying that they ran out of spray nozzles so substituted a replacement nozzle.  I guess they went cheap!  I decided immediately to return this 2 pack to amazon for a refund.  I did not bother to try and open the 2nd bottle to use it because the nozzle will probably break on it too.  The bottles become useless to me if I cannot spray it as intended and I am not about to go searching and looking for a separate spray bottle to transfer the liquids.  Because of the cheap nozzles they switched to, I cannot rate this purchase any higher than the 2 stars I am giving it.

Horrible!  It didn't work and then it leaked all the water out everywhere.

The output of the spray from the nozzle was good. The leakage around the female end and around the silver squares that are inlaid on the female on the very first use was horrible. For the money that I paid for this product I would not recommend it to anyone. The hose I used was a brand new contractors no kink hose from Lowe's ($59.99, not cheap), so the problem was not with the hose, but the firemen's spray nozzle. I will keep on using it because I like the spray output, but I will not purchase another one like it.
