Brand new product is a lemon; would love a simple replacement

Reviewed in the United States on October 24, 2017

Verified Purchase

I purchased this over the summer, but obviously didn't have to use it since it was hot out then. I went to use this heater for the very first time this past weekend and while the igniter worked and I could see the little flame, the disk would not catch or produce heat. I froze in my tent while camping and was sooo looking forward to this heater. This product was expensive and I would love a simple replacement for one that works. Mine still has the tags on it and I still have the box that it came in. I have never used it, its brand new. I'm hoping the owner/distributor will read this and contact me to make this right. thank you.

I Do Not Recommend

Reviewed in the United States on December 19, 2018

Verified Purchase

I've used this heater for a couple months, regularly, and don't recommend it. Brand new it worked great, as time went on it got harder and harder to start. There is a very stiff button that needs to be pressed in to start it, if you have small hands you'll need 2 hands to use it. The last time I tried using it I held the button in for over a minute and the heater wouldn't start. After multiple tries it left me in the cold.

Won’t stay lit!

Reviewed in the United States on November 18, 2018

Verified Purchase

I’ve had many of these over the years and I know they can be, or have been in the past, finicky to light, especially for my arthritic hands. But the latest one I received a few weeks ago just won’t stay lit.

I’ve seen reviews where others have had this issue but I’ve always been able to overcome it with patience and clearing the whole business area of it out with several blasts of canned air, including the little tube where the gas comes out, and with just sticking with it till the thing is “broken in”, meaning, I guess, after I’ve gotten it working enough times it seems to revert to running properly. That does take patience and I’ve always had others to use in the meantime.

I’m not one to take the thing apart like some on youtube. Not that adventurous. But after actually a decade or more, this is the first one I’m returning.

I did notice this new one seems lighter in weight than older ones so no doubt engineering changes get made over time, and product quality goes down to keep profit levels up. That’s business so they say.

It was really cold outside and this helped to get the inside of our tent nice and toasty

Reviewed in the United States on February 4, 2018

Verified Purchase

Takes a little while to get going but this heater really puts out some serious BTU's. We recently used it on a 180 mile overland trip in the high desert in winter. It was really cold outside and this helped to get the inside of our tent nice and toasty. I like the fact it has a low O2 and tip sensor. Not too worried it only has one heat setting because all I want it to do is warm up the tent and sleeping bags in the morning and night.

Too long to fire up

Reviewed in the United States on December 28, 2017

Verified Purchase

Too many delicate safety features. Takes forever to light. Even with an external torch, it takes about 30 sec. to ignite. My thumb has start embedded permanently on it. The slightest motion turns it off. Delicately moving it from one room to the next turns it off. Try to glue some sort of soft rubber medium on the start switch.
After playing with it for about two hours, I realigned the thermocouple closer to the pilot. Now it energizes in about 30 sec.
You think they would make the appropriate adjustments and tests, instead of leaving it to the customer. Why the stupid off switch!?
All you have to do is jar it slightly to turn it off.

Not great for camping like we thought

Reviewed in the United States on April 11, 2018

Verified Purchase

Thought we could use this camping and it would keep our tent warm. It feels warm close up (like right beside it), but it couldn’t keep our tent warm. Maybe the idea is better to use in a deer stand so it can be right up on you? I don’t know. We were a little disappointed in it. It is pretty light weight and will stand up right well even with the propane added.

Great heater, works well, starts easy.

Reviewed in the United States on August 23, 2017

Verified Purchase

Heated a small, bathroom size, space, on a test, up to about 85 degrees. Started up easily. One, one pound bottle lasted about 7 hours. Only negative (miner) is that it is not adjustable. The photographs of the head of the unit are deceptive. It is very large and not portable for backpacking. When properly vented this is a fantastic small heater as backup in the event of heater failure while RVing. Care should be used to properly vent this and any other LP heater in confined spaces. Use a CO2 monitor.

Great heat/er but inconsistent operation

Reviewed in the United Kingdom on January 10, 2016

Verified Purchase

The little heater gives plenty of heat and the gas seems to last ages. The problem you will have is starting it. You have to press the red button (upto) 10 times for a tiny 'pilot' flame to appear. Once flame has appeared, you need to continue to hold in the red button for (for upto 60 seconds they say), then let go and the heater will be at full 're-heat. 'That would be fine if after holding for 60 seconds it comes on, well 8 out of 10 times it does not come on. You find yourself having to repeat the process over and over again. On average I have to do the process 3 times before it comes on, but sometimes upto 10 times (ie: 10 mins spent trying to get it to work). When it works, it works well and it has a great 'tilt' sensor whuch cuts the flames, incase the unit falls over. I would say the unit is a little too sensitive to the odd knock, which I think affects the reliabilty of the unit.

Safe and warm

Reviewed in Canada on July 14, 2019

Verified Purchase

Really loved this product for sour weather camping. We bought this for a festival we were going to where the weather called for rain the whole weekend and thank goodness we did because it’s the only thing that kept us warm. Especially seeing as we were not allowed to have a campfire. It’s very safe, it will shut down if it’s moved or bumped. It’s small so if you have a 20 men tent you probably want to go with a bigger model but this was perfect for what we needed
