Question: What are they made out of and are they comfortable?
Document: It is exactly as advertised. It has three brightness setting, the highest of which is very bright. I expected it would have been class, but it is made of hard plastic - which on hindsight is actually better. Anyway, it is a great product and I'm going to buy at least one more.
I also bought two of these from CANTONI (very high end furniture showroom in major cities). Cantoni has them for $299 a piece, great marketing. They made these sound like they were the best on the market. They had no remote and the color wasn't solid all the way through like the ones are from Design Kollection. Love them and ordering 2 more.
So if you plan to use these on a regular basis, you are going to be porting them back and forth between the patio and wherever your charging station is located, but can't leave it there for more than 4 hours.Overall, it's a very well-made product considering the price tag. But don't expect it to match the build quality of the ones sold by Design Within Reach. But like I said, for the price, it's amazing.
I use them out in the back yard and for grass they do not set stable. Yes you can set on them and they buckle down a bit as you do but without arm rests or the like, I can see them as being something you would want as a seating option and being only 16 inches tall, not comfortable either for most. Again, not for use as a side table really. Just for lighting uniqueness which is quite cool.
they look amazing. battery lasts about 8 hours so you have to remember to recharge regularly. Recommend for sure :)
Well, shipping took a while due to the product being on back-order. I wish the product listing had been updated, as I was unaware of the back-order until a week after I placed my order.The cubes finally arrive this week, and I was very impressed with them. Being LED bulbs, you never know how bright they will actually be until you see it in person.
We've had a couple parties around our pool over the past month and these cubes are a HUGE hit -- perfect as little end tables or as a stool. I wouldn't have a large, heavy person sit on them, but for kids and normal size adults, they're good to go. Don't hesitate to get these if you're looking for some nice smooth lighting on your patio and lots of positive comments!
We purchased 8 of these to use as seating for a digital dome at a conference. They were a HUGE hit! We got lots of compliments. They worked well, and held a charge for the entire 8 hours each day. Also, they were shipped really quickly after we ordered them. Highly recommend!
Totally cool LED lights, great for indoors or outdoors. I really like the blue tone, is my favorite and that's the only tone that I like.
This means you need to bring the cubes inside to charge them.3) the directions clearly state that it is "IMPERATIVE" for you to remove the cube from the charging station as soon as it's finished charging. I was planning on leaving the cubes plugged in at all times, since I don't really need to move them around, and didn't want to bother moving them on and off of the charging station. Well, that's not possible.
Answer: yes
