Question: Is there a warranty?
Document: you pick one of these up and wander through the forest at night looking for gnomes. Theyre all out there usually and fire scares them so you gotta have one of these.
you get what you pay for they are extremely cheap in design and manufacturing not what i was expecting got two of them still working
work great would buy again
well you get what you pay for, for the money I think it might be worth it, I wish I could have afford some better quality
well worth the moneythey are not very bright but add a nice ambiancei am planning on getting another set
was a little disappointed with the brightness of these. but they work good as a boundary marker. for the price they are worth buying. but i will be investing in some more expensive and brighter ones.
very nice lights, they light up at night, which is really nice, I would highly recommend these super great lights as a gift
until my dog ate them. However they went together easily, stood at a nice height that was also adjustable, charged quickly and gave off a descent amount of light.....bad dog.
two broke after one week
though we can not expect lot for this price, the picture is very misleading. There is only one small LED in the centerof the light. The picture shows a very bright light. repending why i bought.
Answer: no
