Purchasing Amplifier Battery
Amplifier Battery by iTEKcanada.com are usually lower in price and usually exceed the performance of OEM Amplifier Battery. Many of iTEKcanada.com’s Amplifier Battery use the same battery cells as OEM batteries.

What is mAh / Wh?
These ratings show battery`s capacity. Think of them as gas in your car tank, the bigger the tank, the more fuel it will carry and your car will drive longer. Same with these batteries, the higher the mAh/Wh, the longer your device will run between recharges.

Will your higher capacity (mAh/Wh) Amplifier Battery work in my device, even though my original battery has a smaller rating?
Definitely! Our batteries are designed to be 100% replacements for original batteries. Higher mAh/Wh rating means longer run time between recharges. The higher the rating the slower it will take for the batteries to drain down. Meaning you will get longer talk time with a higher mAh rating. In other word, higher is the mAh number, better it’ll be for your device.

Quality and Safety
This battery contains advanced technical components and has been tested according to strict CE safety standards. The battery contains a chip that prevents overcharging and short circuiting. Next to this the battery is made from high quality cells that do not suffer from a so-called 'memory effect'.'

Factory Fresh
Batteries lose performance over their lifetime, even when they are not used. Many importers and resellers store their batteries in stock for a long time before they are sold. iTEKcanada.com sends products almost directly from the factory, so you are sure that you will get a brand new high quality battery!

Not greasy at all
Size: 6 Fl Oz (Pack of 2)
This is my first mineral sunscreen. I love that it is not greasy at all. It's easy to apply, and hasn't caused any irritation to my baby's skin.

Fantastic start up
Truskin products are fantastic in my opinion. Not expensive AND effective.. what more can you ask. This 3 pack with Hyaluronic acid, Retinol, and Vitamin C is perfect. I go through the HA faster than the rest so I end up buying the bigger bottle of it. The Vitamin C serum feels incredible on my skin. It feels more moisturizing than the HA. I love using it- just please don’t forget the SPF. This combo pack is perfect for anyone looking to care for their skin. I don’t notice any off putting odors. They all dry down quickly. My skin has not reacted poorly to any of the products. I do stick to my routine of actives(retinol, vit c, tea tree- rotated)to 3x a week and the other days are gentle cleansing, moisturizer and SPF. Since I have switched my skin care routine to TruSkin, I have noticed better looking skin. I’m moisturized with soft youthful looking skin. Recommend and will be buying more.

I didn’t expect this to actually work.
I didn’t take a before photo. Because I legit didn’t expect this to do anything to my skin. I’ve used similar serums before with no results. But here I am, spreading the word because I’m a believer. To describe my skin: aging (mid 40’s), a few wrinkles here and there, nothing insane, very fair, super dry, with an oddly greasy forehead. Minor sun damage, uneven texture and big fat pores that I loathe. Occasional zit here and there. I also have rosacea. It’s the kind of rosacea that turns me bright red when I’m overheated or angry, or if I rub my face too much. It’s doesn’t change the texture or anything, just turns me bright red. My dermatologist prescribed me a cream for it, but warned me that it is the kind of rosacea that is not always easy to treat because it comes from deep under the skin and is situational. The cream was short lived because it dried me out severely. I recently had a trusted friend who is also an oculoplastics surgeon suggest a good vitamin c serum and retinol. He didn’t suggest a brand, just use of the product. So I went hunting on Amazon. This product had great reviews. I figured I’d invest in the three pack since I also knew Hyaluronic acid was a must. My first impressions: Shortly after I ordered it, hadn’t yet received, I got an email from the company offering assistance if needed and gratitude for purchasing product. Good to know I had that standing by if needed. Who doesn’t appreciate a business committed to having happy customers? My first impression for my first uses of the products was positive. Obviously it was too early to see any noticeable changes, but I did like that the serums don’t have smells, they dried very quickly and they’re super easy to rub in. A little goes a long way too. I’m going to reiterate that they don’t smell. Many products say ‘unscented’ but you can still smell something, bad or good. The only one I can mildly smell is the hyaluronic acid and it smells pleasant and clean, but even then, I can barely smell it when I first start rubbing it in. Any smell is gone almost instantly. I can’t describe the smell because by the time my brain realizes I’m smelling something, the smell is already gone. So that’s nice! My impression now, after using it a while: I love it! My redness is greatly reduced. In addition to my rosacea, my very fair skin can be somewhat translucent in places and kind of reveals the semblance of some blood vessels under my skin. This has minimized them tremendously. My “elevens” are lessened as well. This was a big surprise…that wrinkle, along with some wrinkling around my eyes has noticeably lessened. And I want to reiterate that this is all easily noticeable to me without a before photo. It is hard to notice subtle, gradual changes when we don’t have a photo for before and after comparisons - but I’ve noticed. I introduced another item from another brand, and I think that it’s has helped greatly with my pores but I believe these serums have helped too- my pores are barely visible. I am also very impressed by the texture of my skin. I have ALWAYS struggled with uneven texture. I’ve done all the texture improving techniques, tried the products claiming to improve texture, everything I knew to do, with no real difference. But this- this changed the feel of my facial skin entirely. I bumped my own cheek a couple days ago and actually had to rub my face again to ensure it was MY skin I was feeling. It was like a tactile double take. Why? Because my skin was silky smooth. My makeup wears so much better on my skin. My skin looks noticeably younger and brighter and I haven’t had any new zits either since I started. I cannot express enough how happy I am with these changes and these serums. I truly expected these to be items I ended up not using and simply giving them away. But these are staples now. They are worth every penny and a bargain for the skin changes. I look forward to seeing more improvements in my skin over time and I highly recommend this product to any skeptic like I was.

Great stuff definitely recommend at least trying
I've been using the TruSkin Vitamin C serum for over a year, and it's done a solid job brightening my complexion and fading dark spots. Finally gave the full Face Serum Trio a shot with the hyaluronic acid and retinol, and after about a month, it's working great, just like the Vitamin C. The hyaluronic acid hydrates my skin well without any grease, and the retinol's knocked down some fine lines, making things smoother and fresher. Layering them has improved the texture and glow noticeably. No irritation on my sensitive skin. Solid value—I picked this up at $26 when it was Prime Day, but even at that $40 price range, it's still worth it in my opinion since it can last a while. Definitely recommend
