Order was delivered in a timely manner, and both worked as advertised. They work well as controllers for light ampre exhaust fans.I purchased this particular one because one of the other models, first selection was continuous on. Now I know if I had continuous on selection I would be too lazy to pick one of the other selections. I specifically bought this for two reasons one for my cell phone charger and two for my percolator coffee pot. I'm permanently disabled and because of that I'm not in a hurry anymore so I purchased a percolator coffee pot because I'm a little slower than I was three years ago now I enjoy a pot of coffee and I don't have to get off my lazy butt to go turn it off or worried about burnt coffee in the percolator from time to time when I leave the house it's nice to know that the only heating appliance that I use other than the stove is going to be turned off. This is not a timer where it goes on and off but a select timer run only this company has different models that do different things. But this particular one I can plug in my coffee pot push the button one time coffee will percolate and stay hot for 1 hour 90% of the time I'll drink all the coffee I want to drink in an hour now for cell phone charging newer cell phones the regulator will prevent battery damage from leaving it plugged in but still good idea to have some sort of extra seat protection most cell phones now charged up in less than 1 hour fully so with this plugged in not only would you be saving electricity by not running a transformer on 24/7 but you would also prevent possible battery damage due to overcharging. Now I'm not married anymore but if I get married again God forbid this will definitely be plugged into the bathroom for curling irons. Possibly could be used for an iron butt when's the last time you met a woman that actually irons.I was expecting two plugs but received one, it was stated as a two pack, it took two weeks to get delivered, sent me emails telling me it would arrive early but did not! No paperwork, no order information, the plug was placed into bubble envelope.Works great for everything except what the title says it is for! I put all of my nerd credibility on the line when I say that this product is 100% completely useless for Cell Phones, Tablets, and Laptops. All of these devices, and anything similar to them have lithium batteries. Lithium batteries cannot be overcharged*. Why the asterisk? Because technically you can overcharge a lithium battery, but when you do this they explode into an inferno and burn your house down. If your house has not burned down, your device is not overcharging, and you don't need this product.That being said, this product is still awesome for everything that does NOT have a lithium battery. I use it for things with dumb chargers for NiMH and NiCd batteries. Prevents them from overcharging, which hurts battery life for these types of batteries. It would also be nice for things like curling irons, coffee makers, and lamps.I’ve only had this for 2 weeks. I am using it for charging my cell phone at night, so the phone is not charging all night long. It is working very well.This is perfect. I use one for my laptop so I don't over charge it and the other I use for my space heater at work, which makes sure it is turned off when not needed.Purchased to prevent or eliminate cellphone overcharging.Came on time.Arrived without directions...not even the simplest document.Works as expected.Would purchase again.I use them to charge my apple products so that I do not over heat the rechargeable batters. that gives them a longer lifespan I love themI like everything about this product for use with charging my ebike and escooter so the charging won't stay on constantly. It works well in every way after almost a week of use. That being said, one of the two DIDN'T WORK (manufacturer defect). The price is reasonable even if they fail do help me on it but still, pay for two = get two working units right? SELLER PLEASE CONTACT ME.Easy settable times as not to over charge batteries. Use it for Mercane Widewheel Pro and Lectric XP bicycle. A must if you lead a busy life.J'aime bien se produit facile d'utilisations, je le recommande très certainement.A very simple countdown timer for my chargers and heater, working so far
