Question: how to install batteries
Document: Very difficult to install batteries. Needs to have instructions on how to install, not just a video on the amazon page. While my mother liked the tiny lantern, it could be more instructive.
A good product that is very well made and worth the money. The batteries can be a bit difficult to install but they last so long it really is not an issue.
Plan on taking this camping in a few weeks. Have been using it around the house and it works awesome. Small, lightweight, and very bright! The batteries are super easy to install.
Good amount of light from small package. 2 settings nice option, batteries easy to install. Small size allows for easy storage. Will use in emergency situations.
Provides plenty of light in both the power modes. Instructions are lacking in detail or I would have rated it 5-stars. Takes some playing with it to figure out how to install the batteries, the bottom unscrews but doesn't look like it.
Works as mentioned in all positive reviews. It is very bright.Battery install can be improved.It would be better if this has rechargeable batteries so charges during power and comes on when power goes away.Did anybody try using rechargeable batteries(NiMH or NiCD)if this has same brightness?
This is a great lantern. It is compact and the light is very bright. But this lantern does not come with any instructions.It is tricky to install the batteries. I found out how to do that from several of the reviews in this Amazon site. Thank you guys! Also thank "camper" for the instructions on the how to turn on the strobe light.
I should have bought this lantern long ago and need to have more like it around the house. The only comment I really have is that the little red arrows should be on the outside of the case, instead of the inside and while, yes, those who don't like the blinky light and battery drain, can install the batteries when needed ... it is almost impossible to do in the dark.
This is a very nice rugged little lantern. It works well, and contrary to some people's comments, the batteries where very easy to install. The only reason I did not give it 5 stars, is that I would have liked the light to be just a little bit brighter. But it gives off more than enough light to light up a room, to get around, and see what you are doing.
There are no instructions provided with the lantern, so it took me a minute or two to figure out that you have to twist off the base to install the batteries. There are arrows inside the base plate and battery compartment of the lantern that have to match up to replace the base, although I found it easier to do by feel. There is a constantly blinking LED on the front of the lantern even when the lantern is turned off.
Answer: yes
