It dies really fast. I'm not sure if I got a defective item or it's really like this. Disappointed.

Having problems with it already,  it may have been defected,  or I don't know how to use it

Sorry but this was either broken or just a dud.. I put it together correctly and it started leaking so I saw others had no problem, but mine seem to be damaged and hard to use

Whatever it was, it didn't function properly when I got it. I assume it is a sort of stand.

Item was defective when I received it. I know this can happen to ANY item so I'm not gonna pass real judgement yet. I am just waiting now for the information on how to return it and get a new, hopefully, functioning replacement.

I got it and the charger I guess is defective. It doesn't fully charge the battery unless it takes hours and hours. From the reviews I read most of them said they charge fast and that's not the case for me. Really disappointed I was really looking forward to this product.

I don't know if I am just unlucky or it is actually a common problem. But when I received the item, I noticed that one of the two cups size container was missing a green tray that should have been placed inside. It wasn't really worth the hassle of returning it so I am probably not going to do that. However, I am in no way pleased about this.

I hope this is not a common problem. I am only writing this to let people know this particular problem exist and if others notice the same thing, they can speak up about it.

I'm not sure whether it was the packaging or the facility it came from, but the box it came in look demolished and beat up. I had to double check my order invoice to make sure I hadn't inadvertently ordered a used or refurbished item. The product itself seems to be working fine(though it arrived not too long ago today). I'll write an update should I incur any problems. But with the box, I'm very disappointed.

Not sure if I have a defective product of if its normal for them.  The bottom silver piece is completely missing.  Everything works, but it's wobbly and very cheap looking without the bottom chrome colored piece.

I would be embarrassed to put this on my counter top:(

I plugged it in for the first time, to charge it, and the percent of charge display flickers like a bad light bulb. That percentage never goes up. It was plugged in for about 5 hours. Maybe I got a bad unit, but I'm very surprised by all the positive reviews. I've requested a refund and I'm sending it back.

** Update 7/28
Seller contacted me and offered a replacement. They asked me to change my rating. I will do that if the replacement works.

** Update 8/7
The replacement came and it works like it should. The charging ports have different symbols on it which makes me think it's from a different production run. I don't really trust that it will last, but maybe it'll surprise me.

** Update 2/5/2018
It's been working well for more than a year now. I have few chargers. This is the heaviest but it does the job.

I received my Philips Hue yesterday. I immediately heard something inside rattling around. Knowing this was not a good sign, I plugged it in and let it charge for the amount of time suggested. It maybe would have worked without doing that, but I didn't try. After the charging was complete I tried it out. Everything seems to be working as it should, however, I'm not sure I want to keep it knowing that something loose or broken is inside. I may request a new one and send this one back. I'm not sure what to do?

Not sure it if is defective or it won't work for my purpose.  Could be user error.  Lenkeng never responded to my email when I inquired about connecting it for my intended purpose.

I've bought this item twice and both times it didn't live up to work. Not sure what I'll do now

Mine was defective. Looked like it would have been nice, otherwise. I would have liked to try a replacement instead of a refund, but I had bought it on sale.

Unable to post a review describing what was wrong with this item.  I am not sure why.

Well, this might be the first toy thats broken in our household!! Im not happy. I have no clue where the tip of the pen vanished to and now its just a rubbery soft rubber like spaghetti sticking out in front of the pen :( :( :( Initially I thought. Fine. The books don't work well ( they often give wrong answers) But atleast the younger kid like the sounds it make. But, now its just not working at all! Im not sure if this is returnable if the box is not in good shape? :(
