Mastervolt Mass GI 7 is a modern day galvanic isolation transformer, featuring high frequency electronic switch technology. It is designed to sit beween shore power and the on board power to prevent electrical corrosion of metal parts that can occur without this protection. The Mass GI isolation transformer is compact and lightweight, and is housed in a robust aluminium casing. It can be installed easily on a wall or floor, and the unit does not vibrate or hum so will not require rubber mountings. It can aslo be controlled remotely via MasterBus. The Mass GI has a soft start function, which suppresses the inrush current from the transformer to prevent the power fuse blowing. They are also highly efficient, and can be used in parallel to increase the AC power capacity.

love the high neck and crop/waist length
Size: Large, Color: Black, Size: Large, Color: Black
This is one of my favorite shirts- not to loose, but not too tight- has some shape built in. I find the shoulders and neck to be fitted well and look neater than some of my skinnier strapped tank tops -which always seem to hang just a little too low, despite my tall body and fuller upper body, so I don't understand- this looks neater and more put together. I teach yoga and can face my class on hands and knees and not give a show- I'm not prude, but it can be distracting to have a shirt gaping open... the cotton, yes, it's going to age quicker than some fabrics, but I like the feel of it, plus it releases odors more quickly. I have both large and xl size- just depends on my outfit and how I'm feeling-i'm in between sizes so the L is a little more fitted, the xl still looks cute, but gives a little room, esp in the waist- its not as flattering, but cooler and comfy for days I need. I think this shrunk/tightened up a bit in the wash/dry, but not a ton (I don't remember, so think it wasn't much, anyway).

Ill fitting
Size: Medium, Color: White
Arm holes are way too big. I'm 135 pounds and a 36c and it's huge in the chest and too tight around the neck. Its a good length and material but it's so ill fitting everywhere else.

Just ok.
Size: Large, Color: Bright Poppy Red
It’s ok. The fabric isn’t very soft. I expected the color to be more of a coral/pink red. But it’s a red with an orange undertone. Quality is what you expect for $10. I did like the neckline though. It was flattering.

New wardrobe staple for me!
Size: Medium, Color: Navy
I had been buying a similar top at a high price retailer and they were out of navy. Saw this and purchased it. It is actually better quality than the ones I purchased elsewhere for 3xs the price. Super soft and an excellent capsule wardrobe piece to wear alone or under a cardigan or jacket for work.

Perfect First Sneakers for Toddler!
Size: 10 Little Kid, Color: Peri
I bought the Saucony Jazz Hook & Loop sneakers in Peri for my 3-year-old, and they’ve been fantastic! The hook-and-loop straps make them super easy to put on and take off, which is a lifesaver with a wiggly toddler. The fit is true to size, and they’re lightweight yet sturdy, providing great support for little feet. This is actually the second pair i have ordered of this exact style b/c she out grew the first.
The design is adorable, and the color is vibrant without being too flashy. The quality is excellent—they’ve held up well to daily wear and play.
Overall, these are the perfect first sneakers for active little ones. Highly recommend!
