No hassle refund
So glad I bought the plan. After 2.5 years of everyday use of my toaster, it quit working. Contacted Asurion, they emailed a shipping label. A few hours after I dropped the package off at UPS, I had the refund in my Amazon account. Very easy, no hassles.

Very bad
This guys are just an eye wash, they do not cover anything but will charge you. I bought Hand Blender and it broke in couple of months and I took 3 year protection from Asurion. When I contacted them about the issue, they said it is not started, go to manufacturer. I reached out to Amazon and they replaced it for me. Now again it broke. I reached out to asurion again. Now they say it is not contract. what is the point of having protection. Waste of time and money. I will not recommend this to anyone. This is a fraud protection.

Best frother on the market
This company has the best frothers I have ever used, and I have gone through my fair share of frothers over the years trying to find a good one. I bought this frother as soon as I saw they had an upgraded model, although the older model I was using for the past few years was great too (I now use that frother to mix up my dog's supplements :) ). I have found most frothers to be weak, cheaply made, and eat batteries like candy, even ones rated really well here on Amazon. This one however deserves the great reviews. It is well-made and powerful and the newly added 9 different speeds fixes the "problem" the old one had of being a little too powerful at times. The newly designed stand is definitely a major upgrade. The old one was kinda awkward and would wobble, sometimes falling over when trying to put the frother back in it, but this new one is much sturdier and looks nicer, too. The battery life is also excellent. I can rarely remember the last time I had to charge the frother—it lasts a while. And the new indicator makes it easy to know exactly when it needs a recharging now. I haven't looked at another frother in years since switching to this brand. I can't recommend their frothers enough.

✨Happy with my purchase!
At the time of writing this review, I've had my frother for almost a month now, and I love it! Out of the box, it had a good amount of charge already on it, but I did charged it fully before using. I use it just once a day for my morning coffee fix, and it says I still have 80% charge left. I love that feature. I have used the frothing whisk for coffee, which is fantastic, and the regular wisk for scrambled eggs. It works, but I prefer a hand manual whisk for eggs, because I have more control. Even on the lowest speed, it made the bowl spin WAY too much, and I almost had a mess. No problems like that using the frothing wand for my milk though. The dough hook. I have no idea why a dough hook is part of the package... what would it be useful for, one cookie, one bread roll?? I will never used it. The stand itself works for holding the unit, but the holders for the individual wands could be better. I already snapped the plastic on one of them, but not matter, since I'm not using the dough hook anyway. LOL! All in all, I'm happy with my purchase! It's easy to use and clean. It's a quality built frother, the price is fair, I like the variable speed settings, and I love the fact that it shows how much charge is left. Future product improvements I would recommend: make it waterproof, and lose the useless dough hook.
