They turn color after just a week off use unlike the ones I picked up in store so they ended up needing to be changed more often.

If the bulb is turned off with anything other than the remote (eg, wall switch, timer, etc.) it reverts to a color cycling rainbow bulb.  Before realizing this, I was hoping to use them in my landscaping and outdoor lights, controlling each bulb to coincide with holiday themes, but that's not really possible unless you leave them on 24x7 (or remember set them to white every day).

The curtains were perfect, exactly as pictured but after less than a week being up the white turned to an off white.....not sure what happened.

Quite a bit of the black is coming off within the first week

I've had these for like two weeks and take really good care in making sure they don't dry out. I have other refillable fountain pens so I'm aware they can get dry and clogged - but I make sure they're capped and keep moisture in the tip. The black color has already dried up and will not write anymore. I don't do too much writing, just mainly writing checks and an occasional letter. I use the colors for doing my lecture notes. They're great pens and make writing so much easier. The consistency just isn't great and they're not that old at all and I've already lost use of the black.

I had been using these for about 4 weeks now about twice a week (not very often) and only the red lights on one of them still work and on the other the red and green work only. When I bought them they flashed red, blue and green but it didn't last. Since there are such good reviews for the product I contacted the seller and they said this was a one-off as far as they knew and are sending me out a new set free of charge.

UPDATE: The new set of lights have the same issue- this happened within a week one light only the red led came on and the other the lights works but have started to break with only the red and green staying on and sometimes it just shuts of totally. I would probably go for another product instead of these. Perhaps they have a bad batch.

These look really nice. But as soon as I shaved the pegs down the color was off. Even though that's a minor thing I do like them would of got 5 stars if the wood coloring was more consistent.now only time will tell if they hold up to years of turning.

the color faded after a few weeks. Notice the discoloration

These are great! I love it, but within a week one color is already running faster than the other. At first they seemed to drip at a great speed, steadily but not too fast or slow. That didn't last long though, so I suspect cheap construction.

Initially we were very happy with these lights. Bright enough to creat the outdoor ambiance we were looking for until about after a week all of a sudden the lights started flickering. We had not moved them from their original location and we had full sun so not sure why all of a sudden these are acting up! Not sure if I would buy them again. Need to see about possibly returning them.

pretty and easy to use. you just un wrap it and put it in the hole. the bad part is that the color had rubbed off in spots already on both of the ones I got. The color started to rub off about a week after I got them on one of them and then about 2 weeks for the other one.

Really liked the sheets, however one of the pillowcases started turning an orange color after a couple nights sleeping on it. Not sure if it was a reaction to lotion/hygiene products but the second pillowcase didn't have the same reaction.  Now, I have noticed the bottom sheet is starting to turn orange. I've never encountered this with another sheet set before.
