Purchasing Mobile/SmartPhone Battery
Mobile/SmartPhone Battery by iTEKcanada.com are usually lower in price and usually exceed the performance of OEM Mobile/SmartPhone Battery. Many of iTEKcanada.com’s Mobile/SmartPhone 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) Mobile/SmartPhone 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!

Quality Shoe, but slight design issue
Size: 10, Color: Tan Napa, Size: 10, Color: Tan Napa
I like the way these fit and feel. I normally wear a size 10, and these are a 10. Very comfortable to walk in. I think they're stylish enough to wear with jeans or chinos. The leather is nice quality. However, the issue I am noticing, only a few days into wearing these (I've worn 3 times) is that the bottom material doesn't come forward far enough. The tip of the shoe juts out and as you walk the tip rolls forward on to the ground surface and is wearing away at the leather. I mean, I've only wore these 3 times and I am getting major concerns about their durability. I would choose another shoe if I could go back, as these are an indoor shoe only as they're currently designed.

Nice looking
Size: 11, Color: Cognac Grainy
I normally wear an 11.5 (including other Marc Jacob’s- including this make from 2024). The shoes are a pretty soft leather. I had to return for a size 11 which feels slightly tight but now, through experience, I know will stretch. I wear these shoes almost every day in black or brown They look great. Note, these shoes (because all leather) wear out relatively quickly, especially the front. I keep a fake leather Pair (almost identical looking) which are not nearly as comfortable (I don’t take walks in them) but look better for dinners etc.

The "Lazy Professional" Look: Is Hands-Free Luxury Actually Real?
Size: 9.5, Color: Black Napa Leather
Living down here in Florida, my footwear needs are pretty specific. It’s hot, it’s humid, and I spent half my life rushing from the car into work or a meeting. I’ve reached that age where I value efficiency just as much as style—maybe more. I’ve been eyeing the Marc Joseph New York Hands-Free Slip-on Penny Loafers for a while, and after putting them through the wringer, here is the honest truth from someone who just wants to look sharp without the hassle. The "Just Step-In" Reality Look, the big selling point here is the "Hands-Free" tech. We’ve all seen the commercials for those athletic slip-ins, but finding that in a legitimate leather penny loafer is a different game. Does it work? Yes, surprisingly well. The heel counter is firm enough that it doesn’t collapse when you slide your foot in, but it doesn’t feel like a piece of plastic digging into your Achilles once you’re in. For those of us who are tired of bending over or hunting for a shoehorn every morning, this is a genuine quality-of-life upgrade. The Florida Factor: Comfort and Style The leather is actual calfskin (on most models), which is a must for the Florida heat. Synthetic shoes turn into a sauna within ten minutes, but these breathe reasonably well. The aesthetic is classic—it’s a "professor" shoe through and through. You can wear them with chinos and a blazer for work or throw them on with some nice jeans for a weekend lunch. Inside, they’ve got a gel heel insert and a padded footbed. It’s not quite "walking on a cloud"—let’s not over-hype it—but it’s a massive step up from the hard, flat soles of traditional dress loafers. I’ve spent four hours on my feet lecturing, and my arches didn’t hate me by the end of the day. The Sizing Gamble Here’s where you need to be careful. The consensus from other guys (and my own experience) is that the sizing is a bit of a coin toss. They tend to run a little large and sometimes wide. If you have narrow feet, you might find the sides "gaping" or flaring out when you walk, which kills the sleek look. I’d recommend ordering a half-size down if you’re usually between sizes. The Breakdown The Pros: True Hands-Free: You can actually put these on while holding a coffee and a briefcase. No hands needed. Legit Materials: The calf leather feels premium and smells like the real deal. Versatility: Perfectly bridges the gap between a "car shoe" and a formal loafer. Comfort: The gel insert makes a noticeable difference for long-duration wear. The Cons: Sizing Inconsistency: They can run wide, leading to some "heel slip" if you don't get the perfect fit. Break-in Period: The heel is stiff by design (to allow for the slip-on feature), so expect a day or two of minor stiffness. Price Point: They aren't cheap, though often on sale. Value for Money Are they worth it? If you’re comparing them to high-end Italian brands that cost $500, these are an absolute steal. They look 90% as good for a fraction of the price. However, if you're used to $60 mall shoes, the jump to $150+ might feel steep until you realize you’re paying for the convenience of never having to touch your shoes to put them on. For a daily driver in a professional setting, the value is definitely there.

Step In Look Good
Size: 11.5, Color: Cognac Napa Leather
I am wearing these shoes as I write this review, and they look and feel great. I have a bit of a disability with drop foot on the right leg and bilateral neuropathy and have been wearing step in shoes for about 10 years. But the first company that introduced leather dress and casual shoes stopped making them and now only makes sport and casual shoes. So I have been searching for some that meet my need for shoes like this and this company has given me three pairs, so far. Easy to get into, comfortable to wear, and good looking. And they take polish very well, too. (Remember how to do that?). We may buy another pair or two in different styles as well.
