    This is by far one of the most effective anti-aging masks around. I have tried many from Anthony Logistics to Baxter to Urth, none has had quite the fine line reducing, skin rejuvenating effect of the Nickel Mugshot 1.

    A friend of my teen daughter was wearing this at lunch last week and her (flawlessly young) skin had the prettiest shimmer -- not greasy looking or glittery, just a healthy looking glow. I looked it up after she told me the brand and was thrilled to see it was not only on Amazon but it was super affordable, compared with other better known brands of highlighter I had tried. I am so pleased with how it brings light to the areas where I apply it, but it doesnt crease or accentuate my wrinkles or large pores. I use it on my brow bone, lid, and upper cheeks, and it blends without needing blending. Thrilled! I also bought the colorless one -- at this price, I could easily afford both!

    This is the absolutely best lenghening mascara I have ever used. I spend a lot of time and money searching for products that save time and get the job done. Mascara is probably on of the things I have spent the most on. I want a mascara that dries quickly, builds without clumping and lenghens. This fits the bill on all three requirements. I have been using the mascara for about a year and sure enough like so many other things I use, it appears the product has been discontinued. I used to buy it at a Japanese supermarket and they no longer sale it. I went on line with Amazon and found two tubes and ordered them immediately. Now, I guess I have to go back on my quest to find the same qualities in a new product. But Ill continue trying to find this product... .

    I was very disappointed that Lancôme discontinued what is maybe not only their best perfume ,but one of the best perfumes ever created.I bought Connection first in 2001 in Dubai,and I was instantly smitten.I used my perfume very sparingly over the next 4 years,it was my sacrosanct treasure.I am self confessed perfume addict and have experimented with expensive brands and scents over the years, but this perfume is Iconic,the One.You know,like the love of your life-people come and go but you are never able to forget your true love until the end.That perfume has candle like,distinctive,tender ,ephemeral,nostalgic scent -it is not jus a perume,it is a spiritual experience that takes you in another dimension,or at leat thats the effect it has on my senses.Absolutely magnificent.I am thrilled that I found this rare edition on Amazon,and you cant beat the price either for 3.4 ounces.I see there that are only two bottles left for this price and I might well be buying them both soon.

    Ok here it goes.I ordered 3 bags at the same time. Manfrotto & a Lowepro. Lowepro was too small and the Manfrotto was overpriced for what it is. The Manfrotto bag has a weird configuration for your cameras on the inside and the fabric was nothing to talk about, seemed cheap.

    Liquid zinc is vital to the body, and this stuff works great. Originally, I was taking Zinc Assay from Premier Research Labs, but at a price of $14.95 for an 8oz bottle, I found that it just didnt last long enough. Eventually, I decided to try an equivalent, and that is this Liquid Ionic Zinc from Water Oz.

    This product was precisely what I was hoping for. I have been using the powder for a week now and I have no complaints so far. The only thing is that if you mix it with just plain water, it definitely has a bitter taste. I starting adding it to flavored water and it minimizes the bitterness a little. I cant comment on whether or not it actually works yet until Ive been using it for at least a month. Im hoping it will help with some minor joint pain, but also, hair growth and clear skin. Ive heard that some people get fabulous hair, nails, and skin in addition to joint pain improvement after using this product, so my fingers are crossed. If I can remember, I will update my review with any results after using this product for a while.

    I love this curling iron! It is way better than a Hot Tools curling iron. It is a very HOT curling iron, 400+ degrees. It has tourmaline and ceramic barrel and it really makes a nice healthy curl. Tourmaline is a lot better to use on your hair than just ceramic, the barrel is black instead of gold like most ceramic curling irons. I had a tourmaline curling iron a few years ago and really loved it, then it broke one day and I couldnt find another one until now! Give this curling iron a try and I think you will really love it like I do, plus I have been a hairstylist for over 30 years and I do know my curling irons with having to curl hair all day long, we stylist need an iron that is hot and fast and it has to give us a great curl(s) for our clients!

    A lovely feeding kit for any growing child, especially for the Tommee Tippee parent fans out there! I stand by Tommee Tippee products and its the only brand my daughter uses since she was born! This is just another edition but I have to admit, its alot more than I expected, great little Tupperware included that seals up great to throw in a snack in the babys bag, great perfect size bowls in vibrant non fading colors (hot pink & orange) lovely juice cup, a very nice 3 compartment plate & of course the non slip /gripping mat that works wonders making it hard for your child to lift her food of the table! Just a wonderful addition to your childs dish sets!

    I love it! Doesnt leak, stays hot a while, cozy to hug. I like the little sweater--its a little thin, but Im not really manhandling this water bottle in a way that would tear it apart. (If you think you might be a little rougher on yours, Id probably keep looking for one with a sturdier cover.) The only thing Id change is the buttons. Theyre not great quality and I dont like the way they feel. Im just gonna swap em out myself, its a really easy fix.

For professional equalization adjustments, it has 1 INPUT Parametric Equalizer and 1 OUTPUT Parametric Equalizer with gain control, specific frequency setting, and equalizer bandwidth, allowing fine adjustments and detailed equalization control. The Crossover function allows you to precisely define the cut frequencies, attenuation rates, and topology of the LowPass and HighPass filters with Butterworth and Linkwitz-Riley filters (12/18/24/36/48 dB / 8ª).

To aid in the protection of amplifiers and loudspeakers, the DSP 2.8X features a Limiter with Dynamic Attack-Release system that dynamically controls the Attack and Release parameters in real-time, providing security and sound fidelity.

In the audio treatment, it also has Alignment capabilities through High Accuracy Delay, Phase Inversion, Independent Gain by Output and Master Level. For accurate measurements and adjustments, the DSP 2.8X features an integrated Audio Generator with tone generation and frequency sweep, and Pink Noise. Configuration Copy functions between output channels. It also has the functions of Management, Save and Load Settings in memory, Security Password that blocks the editing of the parameters, Marquee / Text Display, and Language Selection.

Sequencer Feature

Allows sequential triggering of other products through the remote trigger connection (REM). Use a cable of at least 20 AWG. The sequencer has three outputs (S1, S2, and S3) which are sequentially activated and deactivated according to the input signal from the remote input (REM IN).

The triggering interval between each output can be set from 0s to 4s. When the set time is 0s, all three outputs will be enabled and disabled at the same time after 3s of the input remote (REM IN) signal change.
