    Love the modern sink!
    This modern, rectangular sink was perfect for my needs. It was easy to order and was delivered in a timely manner. Thankful for being able to order direct and not have to go to a big box store.

    Great product, great service
    I was a bit skeptical of this purchase at first as this was a higher gauge stainless sink than what I had picked out at the local box store (16 vs 18,) plus I got it with extras like a sink grid

    Love my new sink!
    I ordered this sink because it can fit large dishes easily. I am so in love with how easy I can wash even the largest stock pot I own. The first one came a little scratched but customer service immediately sent out a replacement. Although I waited a few more days, it was worth it. Thank you MR Direct for great customer service and making sure I was satisfied.

    The absolute best...
    I purchased this sink in the 14G SS option and it is, by far, the best sink I have laid hands on. Very thick and sturdy material and pretty heavy, almost industrial-like quality. Customer service at MR Direct is superb and I will continue to source all sinks for iur remodels through them.

    Beware of hidden fees
    The sink is nice. I purchased the sink from the store and was charged a $22 shipping fee because they had to get my sink from their warehouse on site. Instead of paying at a cash register, they force you to pay on a computer and charge you a shipping fee even though you are at the store and picking up the product directly from them.

    Great Thanks
    I actually built my own stainless steel countertop so the sink got welded into the countertop and it worked well.

    Price is right!
    Giving it four stars because it's not installed yet, so can't speak to the sound proofing, or spotting, etc., but it is beautiful, the price was far better than many sinks I had looked at, and when there was an issue with the first sink, Erin, Returns Manager, was quick to come up with a solution. I look forward to baking some cookies so I can submerge the entire cookie sheet into my beautiful deep and wide sink!

    I can't wait to get this sink installed. It is big, and looks great. It arrived in 2 days and is better then anything I saw in the big box stores. Plus I would have had a harder time finding the small size I needed. Great Price, Great Look, very Happy.

    Nice sink. I was a little disappointed with the sound dampening "pads" but haven't been bothered by excessive noise. The disposal drain that we installed does not fit the hole very well, and left a gap where the water puddles. I'm hoping it doesn't collect too much gunk over time. All in all I am happy with the sink. It's just the right size, and not too deep. Price was right for us!
