VERY Good But a Few Shortfalls
on August 12, 2015
I struggled when deciding between 3 or 4 stars for this product. In general it's pretty well made and has a good amount of rigidity to it. Also it fits the Nutribullet cups very securely which I wasn't exactly expect, it being an aftermarket product and all. My ONLY two gripes are as follows:
1. The flip top of the lid could use a small upgrade on both ends. The hinge mechanism could do with a bit more friction to keep the top from moving about unexpectedly. Also, the closing end could be a bit more secure to ensure that in the inevitable case that the cup tips over there is a smaller chance of the contents spilling out. Both of these are considerably important especially for the daily commuter or someone that uses this while on-the-go.
2. More importantly, there's no breathing whole for the lid. I've read other reviews that sort of indirectly critique this without really addressing the cause for the issue. The solution is fairly simple actually. All you have to do is add a small hole to the lid to allow air to enter as you drink. This will get rid of the "suction" (not really suction but the creation of a pressure differential) problem. To do this take a wood screw or a nail, place it in the center of the lid at the top (putting it here minimizes the possibility of contents spilling out in the event of the cup tipping over UNLESS it get's nearly inverted OR it's very full) and gently hammer the fastener with a rubber mallet (the rubber mallet will prevent cracking the lid by hitting it too hard). Once you've hammered it several times you'll have to twist it a bit to weaken the material. Perform the same procedure on the opposite side of the lid and you'll have the hole in no time. You DON'T need to and SHOULDN'T pass the whole fastener through the hole, JUST the tip. Clean off the shavings and enjoy!!
If the manufacturer is reading this, I would strongly suggest adding the breathing hole. It's primarily what keeps this from being a 5 star product.
