After about 5 times of use, I started to get flimsy connection. The screen would switch to purple from time to time, and the projector sometimes wouldn't recognize the source and cycle through different source of inputs. It is not reliable so I don't use this for important presentations. Maybe I got a lemon, but for those who are looking for high quality converter, stay away.

i used this power bank just around 3-4 times in a span of 5 months, now it won't charge anymore. maybe it was just a dud. i won't do business with this company again.

I was very excited when I first got these headphones. Affordable and very comfortable. However, they stopped working after using 5 times. Would not recommend.

This worked fairly well for 5 months. As with all my tools, I take good care and flushed and cleaned this vacuum thoroughly after every use. It is always stored inside the garage. Today I went to use it and it won't run. The impeller spins freely. When I plug it in to charge it, the red LED is bright for a half second then is very dim, barely visible. I suspect that water has possibly gotten into the battery or charging circuitry. Can I return this for refund? It should last more than 5 months.

The product worked pretty well for the first couple of times I used it. After about 5 uses, the g key stopped working and a couple of the other keys became very unresponsive. Now, many of the keys have completely stopped working so the keyboard is useless unless you want to use it as a stand. It is also a little annoying to keep taking the ipad off the case to place it on the stand. This is not very reliable and I would not recommend it to anyone.

This works great for about 5 uses!  My first one broke, so I bought another thinking that the original was defective.  Nope.  It's a poor quality product - spend the money on something that you'll actually be able to use continuously!

I used this iron maybe 5 times in a months period, and I turned it on for a 6th use and it would not turn on at all. I thought it was my plug in, changed it to several different areas in my home only to find that the iron burned out. I wouldn't buy it, not worth the trouble of trying to return it to Amazon.

So when I first bought this I would have given it 5 stars as it worked perfectly every time.  After a while though it started to take up to 6 attempts to take off the bottle caps and was starting to leave an imprint on the top of a few of them (I've been using it to remove bottle caps without denting them too much).  I think over time it just wore down a bit and became less effective.

I used the product 5 times. Each time the headphones went in and out. Yesterday the headphones stopped working in one ear.

Updated review:

I changed it to 4 stars as I am impressed with the customer service. Shortly after I posted my review I was surprised to get a replacement in the mail.

I never contacted the manufacture as it was few months I have had it although I had only used it a few time.
They must have seen my review and took the initiative to replace it!
For that I am very impressed!! Hoping to get better results from the replacement!

Original Review:

Used about six times and it no longer works. Avoid!

Like many other people here have said, this product stopped working after a total of 5 uses. The espresso was no longer hot, the frother no longer frothed. But prior to it breaking down, it worked like a dream. I have ordered a second to see if this a constant. I have my hopes high that it is not.

Works well for a short time, but needs to be reapplied multiple times...

Ripped after fifth use. Not very sturdy construction.
