I have ordered this mug twice now. The first time I was so excited, and anxiously awaited the arrival of my cool new copper mug! Instead, when I opened up my box (which was clearly made for the right mug) I found a black plastic one instead.. the suction function worked though, so I forgave all and ordered my refund, and reordered the same item. Just got the second order today. This time it's the right mug!! Just it doesn't work AT ALL. The "vacuum" doesn't exist, and it leaks out of the top also. Do not buy this mug. I really tried. I'm sad now. Do not buy this mug...
It worked great for the first six months and then lost its special no tipping grip. I thought not a problem since it has a lifetime warranty. I submitted a warranty claim on their website and received an email that said "A support representative will be reviewing your request and will send you a personal response.(usually within 24 hours)". I waited for over a week and then left a message on the "Get Mighty" website for a status. I received a response from the founder (Jayme Smaldone) letting me know that he will have Val work on my warranty request immediately. That was over two weeks ago (August 17th). Total wait time is one month and counting.
Bottom line, good product (when working) but terrible customer service and support. Loyalty is built on customer service and this company sorely lacks in this area.
When I first received the mug it came without a seal for the lid and it rendered it useless. After a few customer service requests to MIghtyMug and only getting auto-responses, I temp-fixed it with a 2 1/2" diameter o-ring from the plumbing section of a local hardware store. After that I have used it consistently and it has saved a few spills already. I did end up getting a real response from MightyMug and after a little more back and forth they sent a new lid -- this time it came with the seal.
Pros: No-tip feature works great. Can be knocked over with just the right hit, but even if it only stops it from falling 3/4 of the time I would be happy. From some simple testing/knocking fun, it appears that it would stop around 95% of the accidental tips.
Biggie Stainless Steel Tumbler is nicely insulated -- Keeps coffee hot very well. I haven't timed it and don't care to - it stays hot till I am done drinking it :-)
Pro and Con --- Customer Service -- although slow to respond (beyond the auto-response) they did end up sending a new lid/ backed the product.
Cons: Lid could use some re-designing--the lid is difficult to use with one hand. The part that closes the drinking hole is hinged and snaps tightly into place. The problem is that it is difficult to close with one hand. Would much prefer a sliding/turning style lid that can be opened/closed with ease than one which requires both hands to be free.
The smart grip technology only lasts about 6-9 months based on normal use. It is an okay mug. It is not a Yetti or something similar in keeping the original temperature. Since it has happened on both mugs I bought, I figure this will happen to others as well.
Either I received a defective one or this mug is really useless. The idea behind it and the system at the bottom are great But it does not compensate for the poor quality at the top of this mug, you can't simply drink from it without spilling and getting it everywhere.
My 86 year old mother spilled some coffee at her weekly card game a couple of months ago. She was so embarassed that she has neen bringing bottled water since that day. She loves her coffee so I was absolutely thrilled to hear of the Mighty Mug. I showed her how it worked and taught her to lift it with ease etc. She really was thrilled to be able to bring coffee this week and also was going to show the mug off to the other old ladies.
So I am standing talking to her as she began to rinse it for first time use, and I look down and see dark brown water running over her hands. For a very split second I thought she was bleeding and blurted out "what happened?" Well, she had been looking at me the whole time (so was obviously not in pain or cut) and she looked down and brought her hand to her nose and declared "it's rust".
Underneath the orange pad at the bottom it is caked very heavily with rust. When she was rinsing the bottom it flowed out. It was an extreme amount of rust. I have no idea how that happens on a brand new, in the box mug. All the labels were still affixed, the box was pristine, and had no indications it was ever handled by anyone, much less that it was someones return. This tells me that 1. the mug was obviously exposed to water during manufacture, and 2. the area underneath the suction cup - at least on this mug - is not rust resistant. Rust resistance is pretty important for a coffee mug.
I have reached out to Mighty Mug and don't know if I will get a reply as it seems others have had no luck. If I get any feedback I will update this review.
For now, whether you just received it or had it for a bit, I suggest you check for this heavy rust. By using the sink spray attachment for just a second the rust began to flow. Rinse or spray some water over the base of your cup and make sure nothing flows out from under the orange base.
It really sucks that this happened because the mug stood up to every bump and smack test I threw at it. Both my mom and I were absolutely shocked at how well it works. If I can hear back a decent reason why this was an anomaly I will purchase again in a heartbeat! In fact, I will give it a day or two to see if Mighty Mug answers my email before processing the return. because I have a choice for "replace" or "refund" and I need to know which box to check.
