Designed to withstand the elements, the M2-300X4 Element Ready™ amplifier is a 300 watt, full-range class-D model, capable of operating at 4Ω or 2Ω stereo, and 4Ω bridged/mono. This amplifier is extremely efficient because of its class D technology which reduces demand on the electrical system. The amp also features C.L.E.A.N. circuitry to help you adjust your gain settings, a P.O.W.E.R. Supply that generates more power as voltage increases.
The M2 Series were developed for marine audio environments that feature UV resistant protection and special internal conformal coating that protect the electronics from water. It’s designed for those who want a reliable amplifier – with all the power and performance you’ve come to expect from Rockford Fosgate – at an economical price. Rockford Fosgate amplifiers are renowned world-wide for being “under rated,” easily surpassing all specifications, and most importantly, generating more power than their ratings. The latest generation of M2 Series amplifiers are also designed to be easy to setup and configure, making them perfect for use in any application.

Moisturizing Gloves That Actually Work
Over the years, I have tried so many different types of gloves to alleviate my dry skin. Since it especially bad on my hands I have tried everything. Of all the gloves I have purchased, this pair is head and shoulders above all the others. The first night I used these I could not believe the difference! It was astonishing. My hands were soft and supple for the first time in my life, and they stayed that way for most of the day. The moisturizing aspects of leaving humectants on one's skin for prolonged periods is really a game changer. They fit perfectly and can be pulled on with ease. The crazy bonus is that I was still able to use my phone once I was wearing them. That has never been the case with any of the other gloves I've used. If you have dry skin on your hands, you must try these. One night of use and you will be sold!

A bit small for one size fits all
Purchased these for my husband who has pretty severe dry skin in the winter. The gloves are great but they are a bit small. My husband doesn’t have very large hands (cadet size golfing gloves) & this hardly reaches his wrist so one size fits most is a bit of a stretch. However, these do the job & he likes them. We appreciate the packaging doubles as a reusable pouch.

Awful
I love this brand & expected more, especially for the price. the gloves are super bulky and uncomfortable. they’re hard to get on and off and have a strange feeling when on because of the gel lining. they also smell odd. i wore them so about a week with several different creams/balms/lotions etc. i woke up with them off multiple times which makes me know that i was uncomfortable in them during my sleep. they also caused a weird breakout on my hands up to my wrists that took over a week to go away with the help of cortisone. it was like hives but more rash like. i didn’t bother attempting to return them and decided to throw them out. waste of money, time & ended up with a rash at the end. they did make my hands softer and helped with my cracked skin but at what cost?

Update - Stick to your hands
UPDATED - I am SO impressed with the seller!! They read my review and gave me a full refund even though I no longer had the gloves to return. At this point I would suggest that you aren't taking a big risk to give these gloves a try, a lot of people obviously love them, and if you don't you can certainly get your money back. Many thanks to the excellent seller!

I bought these because it seemed like there were a lot of good reviews. I hated these! I don't understand why anyone liked them... they are lined with thick sticky gel. You know those gel like sticky toys that kids toss at a wall and it sticks? Or do you recall the sticky, gummy hands that you could toss and they would pick up a piece of paper or something? The lining of these gloves make me think of those toys. So my experience is that they are very difficult to get on and once they're on they really bugged me after awhile I need to get them off, but they're very difficult to get off without turning the gloves inside out. ...then you have to try get them turned back to right side out... in the end I tried them and then thought I would try them one more time but they were such a pain in the rear that I ended up tossing them in the trash because I waited too long to be able to return them. One of my saddest purchases from Amazon!

Hallelujah!
My hands were so dry and cracked until I got these babies. I didn't realize what I was getting myself into and was surprised when they were lined with some kind of silicone. Night one, I lathered my hands with whatever lotion I had laying around and went to bed. Now, these gloves are not super comfy because they're so thick, but not so bad that I won't use them. Anyway, wore them several hours and took them off in the middle of the night (they recommend at least 20-30 minutes). In the morning, my hands were baby soft. No cracks. No dryness in sight. AND it lasted all day. I did it the night after and I have not had dry hands for nearly 2 weeks! It's insane. I'm SO happy. Definitely worth it as a little treat yourself.
