"For better performance, better batteries are needed."
I got this at a local Discovery Channel store for $41.97. The first one I got had a broken rear leg. Robopet just shutdown itself couple minutes after I activated it because it couldn't turn over and stand up. After I examed it I found the parts is detached from the motor. I went back to the store and exhchange for a new one. The new one has 4 black chips that scure the leg parts and prevent the parts from detaching from the motors. Obviously the first one is defective...lacks of parts.
Before I got the robopet I've heard that batteries affect the performance a lot. I went to Frys and got 2 different kinds of batteries, ACDelco Super Alkaline and eneloop rechargeable by Sanyo and GE, to test out. I was very dissapointed on the performance after using ACDelco. What happened is Robopet had problem turnover and standup after it did the rollover trick. Then I used eneloop batteries. The performance improved but still... Robopet had to try like 3 times to stand up, sometimes shutdown itself, and had problem making turns on the carpet. But the performance is OK when it's on hard floor. I can tell the waist of Robopet was weak from the sound of the motor...dying sound. I thought I got a defect one again or Robopet doesn't perform well on carpet at all. I decided to try the old batteries, Sony CycleEngery, that I use for my mp3 palyer. The performance is owesome. Now robopet makes turns rollover nicely even on the soft thick carpet.
At beginning I thought Robopet's sensors were not working very well since it kept bumpping into walls and walking against the wall. Then I found that if the light is bright enough Robopet reacts very well.
Some maybe said that it's made of cheap parts. But I think for about $42 it's totally worth it. Sony Aibo costs more than $500.
I am gonna order the Roboreptile from Amazon. I can't wait to receive RV2 next Tuesday.
I would suggest exam the products right after you purchase since missing parts, 4 parts, is a very riduculous thing that could happen. And they assert that each product is tested before they ship it.

"Cool toy, But has some durability problems."
It is a really cool toy if the price is at this level, not the original WOWEE retail. It can act like a real dog although it can only show routined action. It walks well on a typical carpet floor - It is 4-legged toy!!! - So its walking ability is best among all WOWWEE robots. Only Robosapien can be equal to this toy for walking ability. Neither RR, nor RS V2(RRep) can walk better than robopet.

In addition, its articulated leg structure is a fun itself! Maybe Zoids can only match with it in that viewpoint. Of course its walking motion is more realistic than zoids.

Durability problem lies in the fatigue failure of the plastic grip of a spring in rear legs. This spring is needed to recover rear leg to its original position when the robopet shakes his leg for the trick #9. The problem is that its grip made of plastic is too weak. When you have played robopet for a long time, check this problem and remove the spring when its grip is broken.

"Recommended to Everyone!!!!!!!!"
As thrilled as I was when I bought the Roboraptor, I decided to buy the Robopet. At first, I was a little skeptical about the purchase because I hadn't gotten to research it yet, but I agreed to give it a chance. When my dad and I tried it out, it was better than I thought it would be! Even my little sister loves it! I would definitely recommend it to everyone, especially robot freaks like myself. Enjoy!

"Lots of Fun!!!"
My daughter really loves this toy. The funny thing is that my husband plays with it more than she does!!!

"I really wanted to like it"
I wanted a robotic pet for our busy family, so I bought the original RoboSapien when it first came out. Though we had a lot of fun with it, it lacked autonomy (the ability to do things on its own). Robopet promised that, so I bought that next for my family. It looked promising!

At first, it was immensely fun. It seemed to deliver on its promises. It could roll over, sit up and beg, and scampered about as it explored its environment without running into anything. However, I was disappointed with the fact that it had trouble on a threshhold (the raised part where one floor type changes to another floor type), and could easily get itself stuck in a corner with only one or two obsticals. Oddly, uneven and soft surfaces posed a great challenge; one would assume that a walking robot with four legs ought to be able to walk on anything, but robopet needed a hard, flat surface. Also, I questioned the durability of this 'bot.

Now, I'm not sure if it's something that happened when it fell 6" to the floor after backing away from a wall, or if it was a defect, but mine started locking up whenever I used it in edge detection mode. Nothing takes the fun out faster than when this 'bot freezes in some odd pose and becomes completely unresponsive until it's reset; this after only a couple of minutes of play.

I did some research on my problem, and discovered other durability and quality issues. Apparently, the gears inside are made out of cheap plastic and are prone to stripping. The legs aren't very strong at all and they are also prone to breaking. This wouldn't be that big of a deal if spare parts were readily available, cheap, and easy to replace, but this is not the case.

I'm sorry, but a robotic pet needs to be reasonably durable. If it walks, then it needs to be able to walk on grass, carpet, gravel...and finally, it ought to be able to tell you when it's "Hungry" (low battery power) at the very least. If you want to get into the world of robotics, I suggest one of the many good kits, and if you're in the market for a cheap robotic pet, wait a little longer. Robopet does come close, but we're not quite there yet.
