Bests & Worsts Reviews from Amazon

Works well and easy to use, but deceptive practices involved. You can use it for free with a 20 lb tank, but if you want to use it for a 30-40 lb tank you will have to pay fees to monitor your tank. I personally think that hidden fees outweigh any quality in design or manufacture. Why not be up front with people? Why does it cost more to monitor a heavier tank? What’s to stop them from deciding I have to begin paying for 20 lb tanks? If they had explained that additional cost, I would have never purchased this item. I guess I have my answer. It’s worth keeping, but I have plenty of doubts about it lasting. Can a company that operates deceptively have any real concerns for quality? I doubt it.
