I bought these and the FIRST time I dropped the board down to ride, the battery pack fell off. i tried layers and layers and layers of ductape but NOTHING helped. If your not serious about riding a board, then go ahead. But if you have any experience, DO NOT BUY!!!! I got them in the daytime and they didn't even make it till night. They glow bright but you cant go anywhere withought the battery pack falling down. I honestly feel like i wasted my money buying these things, and i don't reccoment them to ANYBODY RIDING AT MORE THAN 1 MPH! I may come off as rude, im just mad that i wasted my money on these. Thank You and I hope you take my advice.

It worked great at first, but now hesitates and won't go over 2k rpms. Very disappointed.

Edit: Amazon is zero help resolving this issue. They want me to contact the seller, although the seller won't respond. Avoid this tach

in the first 2 weeks I had two of these literally FLY off my car with the window cracked while driving about 45-50mph.  The vendor has been very agile in replacing them as well.  All  and all, I wish I would have gone with the OEM stick ons right from acura.....

Other reviews with positive feedback are from people PAID directly from this manufacturer to buy this product so they can leave a positive verified review. DO NOT be fooled!!!

This products output is NOT even close to 30mph winds yet they claim 215MPH. Pathetic lying manufacturer! Wind is NOT directional (meaning focused like a laser) its more like a ceiling fan scattering wind everywhere making this product completely and utterly ineffective...

DO NOT BUY this product.

Instead buy "Greenworks 204012,"my neighbor let me borrow his and it blows an extreme amount of wind in a single direction like a laser focus.  Highly effective and recommended!

Bought this to replace my still good hand pump turned out tho it was shipped damaged by seller.  Unfortunately it's not like I pump air to my bike tires everyday and found out of the issue deep in the trails adding 45min walk back to my car.  What's more unfortunate it's that's my return window is now closed.  Point here is.... DO NOT BUY.....!!!! @$&%#&!!

DON'T BUY THIS!!! only ONE of the back wheel is powered through the motor. As a result, it is useless when ever you hit small hill or a small slope. because it will not not move. Work fine in flat land. Just like the previous comments: I don't think this goes 2.5 miles and handle does not secure properly to the streering unit (there is little play)
Everything else is as explaned in the product description and nothing wrong.
Just don't understand why they didn't power BOTH rear wheels!!!! extremely disappointed becuase they TOTALLY left that out in the product description!!!!!

Be very careful before you buy this product.  The ad is very deceiving.  Though they show this unit starting a small truck multiple times in succession. My experience was completely different.  A fully charged unit could not even turn over my Honda Pilot (6 cylinder engine)one time !!. It has very low amperage and not enough for this car let alone V-8s.  I am completely disappointed in this unit  and now is too late to return as I did not have occasion to need/try it within the specified time period.  So try it out immediately if you do buy it or check the minimum amperage to start your car before buying such a unit

I had a mechanic install this part and he immediately asked me where I bought it. I told him through Amazon and he said he figured because I actually received a re-ferbished part and that it would not work like a new part would have. He then started to show me how slow the motor is, and that I will never have a normal, fast working whiper with this part. He instructed me instead next time to buy directly through the dealer as this was not worth the money. I have noticed in traffic here in the big southern heavy rains that it does not perform like a regular whiper motor should and cannot work fast enough to keep the rain off. I am very unhappy with this part and the lack of power the motor puts out to operate safely.

So, I finally bought a new set of tires for my car and had the beads installed, had a front end alignment performed to ensure I would get good results and a great ride. Boy was I wrong, sometimes it would be pretty smooth other time it would shake the whole car, sometimes it would shimmy. Please do not waste your money purchasing this product. It is NOT made to be used in passenger cars. If you Blog this product, you will discover its not for cars but for big trucks or motorcycles. I will now need to have the tires dismounted, the beads removed, tire remounted and balanced. So as a consumer I will need to spend additional funds to correct this issue. I did read the reviews on Amazon before I purchased this product so I felt I was getting a proven product but I think I have been misled.

Not pleased!  This computer auto-pauses while climbing steep hills on my MTB.  My rides end up averaging 10% shorter and 50% less climbing than everyone else who are using Garmins or Strava.  Wahoo's answer is to buy the speed sensor.  My Garmin and my phone don't need that, but if your computer needs it to work properly, include it!  For $330 for a bike computer, I shouldn't have to buy extra parts to get an accurate distance or elevation measurement. Truth told, I ordered the speed sensor and if it fully fixes the problem I'll keep the elemnt,  but if it isn't 100% I'm sending it all back. If you're buying this for mountain biking where your climbs may be below 4-5 mph, beware.  do some research before you buy.

DO NOT BUY!  Pump failed after 2 1/2 months of use.  Warranty on this site states 365 day unlimited mileage warranty.  When I contacted the company they stated they would only issue a refund after 30 days and would offer a replacement for the remaining 11 months.  Well, after my vehicle was left inoperable from this defective pump, I could not wait for them to send me a new replacement.  I could not go without a vehicle for that amount of time.  I needed to buy a new pump that day and install it.  A fuel pump should last many years, many miles, not 2 1/2 months.  Obviously this was a defective pump and the fact that they would only send a replacement tells me they don't back their product.  Read all the reviews on this product on this listing and others.  THINK TWICE BEFORE BUYING!!

This "siren" is a great price. However, it should not be advertised as an emergency vehicle siren.  It is very cheap built, low quality. Vehicles in front of you cannot hear it above about 40-45mph.  I would recommend this siren only for public events to get the attention of pedestrian traffic, not attention of vehicles. After a short time of using this cheap system I returned it for a refund and bought me a very well known name brand emergency vehicle siren system-- one that meets all requirements of such.  I would avoid this at all cost if you are wanting a system that will warn vehicle traffic during emergency response. Thanks!

I purchased a set of 4 Falken Wildpeaks 275 70 r18 on June 5, 2018 from amazon in anticipation of preparing for a long road trip pulling a 22 feet travel trailer from California to Yellowstone NP.  On the way home west on the 70 interstate just west of Rifle, Co., I experienced a blowout of the front driver side tire going approx 60 mph.  The tires only had approx. 3000 miles on them.  I managed to pull onto the right shoulder and discovered that the tire a blown out the side wall in numerous places.  I have attached pics.  You can see that tire is still brand new with deep treads remaining.  I don't know how many other people have experienced this with these tires but it was one of the most scary experience I have felt behind the wheel.  I had AAA put on my spare and I drove to the nearest tire store (45 miles)and replaced all 4 since I did not trust these tires anymore.  I do not recommend these tires a would like to get a refund..

This thing is HORRIBLE! My 1 year old son received one of these yellow H2's from his Grandpa this past Christmas. It took a few minutes, but was fairly easy to put together. Charged the battery for 18 hours. Took my son outside, all he could do was step on the petal, but he loved it. He started riding down the driveway. The first thing I notice is that this H2 had virtually no traction. Even on the driveway it spins the wheels. As far as riding off road at all, even in grass, forget it. So he road about 150 yards and the battery died; I ended up pushing him back.

This thing could barely pull my 1 year old!

So, the truck ends up sitting in my garage until spring. I stored the battery with a full charge (18 hours). Today was the second day we took the H2 out this spring. Again today, I ended up pushing my son, now 2, up the driveway. So after a little bit of searching I found this customer no-service number, 1-877-743-3899. All they told me was my product was out of the 90 day warranty and they couldn't do anything for me, unless I wanted to buy a $30 battery.

No, I'm not going to buy their battery for $30. I'm going to walmart to buy a real power-wheels battery and charger, and I'm going to MAKE it work.

From this point, I will not be buying any products made by 'National Products LTD'

For everyone who will need parts for this, and you will need parts, I found this website...

Sorry to everyone for sounding so negative about this little H2.

The only good thing I can say about it is that it looks REALLY COOL!

My 5 year old had a pocket rocket that would reach 12 to 15 mph.  We thought the minimoto maxii would be the best step up, since the size is a little larger and on the box it indicated the speed of this product was 18 mph.  Now online it's only stating to go 10 mph.  I'd be highly surprised if it goes that fast.  Also, as soon as it hits grass it seems to virtually go dead.  I would not recommend this product unless you're putting a complete beginner on it and you live in a parking lot!
