Super fun, works as advertised

I ordered these light to replace an old rope light that illuminated the space above our kitchen cabinets. They light the space SO much better, and I am having a blast using all the different colors, depending on my mood. They were super easy to set up.  I have mine plugged in to a timer, so they come on at night and go off around 11 PM. They will default to whatever color you last set.  I am enjoying them so much I am giving them away as Christmas gifts this year.

I bought one of these just the other day and am having a blast setting it up in various goofy poses. These things are so much fun, it makes me wish they had some kind of purpose.

Obviously if you're looking at this accessory, you either own the Overdrive Track or you're looking at investing in one.  This accessory is as fun as it sounds.  I was worried that due to the robotic nature of the cars, and their relatively high cost, that crashing them into one another was the last thing I wanted to do.....however that little boy in my head kept telling me it would be a blast.  Well, the little boy was right, and the Collision Kit is every bit of fun you would hope it to be!  The near misses are more thrilling than the collisions, but watching the cars drive the wrong way around the track or searching to get back on the track is hilarious!  This is by far are favorite accessory for the Overdrive system!

Great toy that works well. The battery chassis is a bit hard to get to and when extended the main activation trigger doesn't work due to a design flaw when the screwdriver is extended. The secondary button works fine though.
Otherwise, a lot of fun!

When I opened this toy to get it set up for my son's birthday, I discovered a big problem. One of the batteries had corroded a spring that holds the battery in place, therefore the battery woudn't stay in place. Fotunately, someone knew to use folded up tin foil and cram it in the space, and luckily that worked. The toy worked fine with that quick-fix and it was a HUGE hit at the birthday party (5 and 6 year-olds)and even at show-n-tell for his school. This is the most entertaining toy we've had for a long time. It's tall and moves slowly, the voice is definately robot-material, it leans when the air gets a little low (an easy fix), but it will be a favorite for a very long time.
If you want lots of laughs and entertainment, this is the perfect toy to get. It's been hilarious to watch children play with it and we've been caught manuvering him around a few times ourselves!

This is what I've come to consider a geek's toy.  The learning curve is sizeable but the fun you can have tweaking this thing is unlimited.  It would appear that some of the reviewers here just didn't dig deep enough to uncover certain features.  I could quibble with some of the menu logic, the main screen being too dim in daylight, the lack of a manual mute (!), and above all the tiny buttons, but once you've adjusted everything to your liking, it's quite impressive.  Sound is A+, phone operation flawless, HD radio reception (in DC) fantastic with virtually no dropouts, display colors matched my car's exactly, etc.  Now about teaching the other family members how to use it....

I've had so much fun with this little device.  I bought it to brush up on my soldering skills before attempting an intricate build.

Easy to build, instructions were fine, could have been better, but once I got the "flow" of them it was a breeze.

Fits in your pocket, and can be used and aimed without looking at it.

Only negative I have is not something that can improved upon and that is that it has to cycle through all known codes, and that can take a few seconds to a minute to actually turn the TV in question off.  First time I used it, I thought I'd built it wrong because nothing happened at first, then about 5 seconds later, all the TV's in the place that were facing me turned off.  Talking about 15 televisions.  I nearly choked on my beverage.

The immediate uproar of half the people in the crowd made it worth it.  If you do it during a big game for best results try to time it during a critical play and don't get caught doing it unless you want a whooping.

This is fun for the whole family (including the dad) and the neighborhood kids who come over love playing with it too. This was a Christmas present for our 8 year old daughter and although it was not one of her first gifts to open (we didn't have the right sized batteries and couldn't find a small enough screwdriver, plus we needed scissors to open the package and they had been misplaced), nonetheless she loved them when she finally got them opened and working. We listened in on a conversation someone else was having in the neighborhood... turns out they had also gotten a set of walkie-talkies for Christmas (two brothers). That part was fun. I'm sure we could have communicated with them but we were all too shy to say anything. Apparently this picks up signals from pretty far away. It can scan channels to find open channels or ones where people are broadcasting a signal. It has two settings for Hi or Low that can pick up signals from far away or save battery life and only pick up signals that are closer in range. Clear reception, no static, and has a little light on top, does not drain the batteries quickly. I think we've gotten maybe 10 hours out of this so far and have not had to change the batteries yet.

For the price, this is about as much fun as you can have. Easy setup, easy to learn, and fun as heck. Camera stopped working after a few flights, hopefully customer service is nice :)

So much fun!!! So disappointing as well :(
Worked only 2 days before it wouldn't charge! Thank you to Amazon who is sending out a replacement. I strongly advise: DO NOT PURCHASE THIS WITHOUT A WARRANTY. I haven't dealt with warranty yet, but after this first experience, I would not risk going without. I will update more as replacement is tested.

So far, though:
An absolute FABULOUS toy when it works!! The talk of the neighborhood- both kids and adults!
My son is 7 and very small (41" and 38lbs). He handles this thing like a beast! I was concerned that he wouldn't be able to reach the footrests, but no issues. My 11 year old daughter loves it and rides it as well. This thing FLIES!

It was extremely easy to assemble; despite what some reviews had mentioned! I read some reviews of part of it falling apart. Can't comment on that since we only had it working 2 days! When it did work, the charge lasted a decent amount of time for zooming around our neighborhood. Long enough for the kids to enjoy it and have lots of fun. It seemed reasonable enough, and I have no complaints concerning that.

If you follow the directions, you'll jump with joy.

Recommending it to all my friends

This runs well and loads of fun for a 35$ toy.

There are a few tricks to getting it to start up:
-Set transmitter next to bike
-Turn on transmitter
-Turn on bike while the transmitter light is still flashing (you only have ~5sec)
If you wait too long the transmitter will stop flashing, and the bike will not start.  In that case turn both off and try again.

Run times are about 10-15 min from a charge of the bike (off of a USB cable).  Bike takes about 15 min to charge as well.
It is also surprisingly durable, with nothing broken yet even with many full-speed runs into curbs and ditches.

After 2 sessions my 7yo daughter had it all figured out and can drive it around with minimal crashing.

I was surprised at how much fun this toy was - both for my son and me. My son has enjoyed it, and I have actually plugged earphones into it and strummed happily along for an hour or two.

The strumming feature works nicely. No, it's not strings - but what do you want for the price? It's a winner.

I love the concept - and it works as advertised.

This is a fun little toy. My kids aged 5 and 3 love it.  Of course, I supervise, but we talked about counting, how the sparks work and practice taking turns.  The sparks are a great effect and they like seeing how it looks different in the light and in a darkened room. The gadget feels pretty sturdy, but certainly would not withstand any physical abuse. I was surprised at how actively the kids engaged with it. The big winding key is a nice touch. It makes it easier for small hands to wind. Incidentally, my adult friends liked watching it as well and began immediately speculating how it worked. It's an interesting diversion at a reasonable price.

Oh my god this thing is stupid fun. I used it to back light my wall mounted TV because $20 and why not. I've read others complaining about the adhesive, but mine worked fine. One really odd quirk is that the IR code for my Visio sound bar and this unit use some similar blast codes. Namely power, and weirdly some of the color codes. Using the remote to turn down my volume results in a dark green back light, and if I put my soundbar into BT mode, I get a dim white. It was kinda funny, until the color remote no longer worked appropriately (adjustable colors and color pre-sets don't work), and there doesn't appear to be a means of re-setting it. IF you need to be able to get color specific, AND you have a Visio sound bar, that's a deal breaker. However, I just leave mine on slow 7 color fade and don't worry about it. I get tons of comments on it from friends and it adds a very pleasant ambiance to movie night, providing adjustable lighting without the need for overhead or lamps. Installations was pretty easy, and there are *tons* of accessories for it that allow for a lot of customization. I love mine and can think of a lot of different uses if I wanted to get crazy...
