Frequently Asked Questions
At what age is my child ready for a belt-positioning booster like the Tanza?
The Tanza is intended for children who have outgrown their forward-facing harnessed car seat and weigh between 18 and 45 kg (40–100 lbs) while measuring 110 to 145 cm (43–57 in) tall. Most children reach this stage around age four to five, but always check your current car seat's outgrown limits first.
Can I install the Tanza without the UAS connectors?
The Tanza is designed to be used with its rigid UAS connectors for a secure fit. Refer to the product manual for your specific vehicle compatibility and installation guidance.
Is the Tanza allowed on airplanes?
Belt-positioning boosters rely on the vehicle's lap-and-shoulder belt and are generally not certified for aircraft use. Check airline policies before travelling.

A Sturdy Spice Rack With Some Perks and Some Limitations
We really needed a new spice rack that holds a variety of bottle sizes, and this one is made for a pretty brand-specific bottle style. It does hold some of the older model metal containers, so it looks like we will be adapting to the newer sizes and shapes. This organizer is easy to assemble and fits the space I designed perfectly. The bottom shelf is very sturdy, and the top shelf is not quite as solid, and I'm not sure exactly why.
One thing is for sure: when you fill this spice rack to capacity, you will have all the spices necessary for a well-stocked kitchen. We have not filled it up, but my guess is that we can fit between 35 and 40 individual spice bottles and cans.
Overall, it is at the higher end of value for the money, but it may serve us perfectly through the years and prove itself to be an excellent value and keep all of our spices well organized.

Very nice pull-out spice rack for square bottles. Mount with screws for permanence.
This Boivshi spice rack organizer is made with stainless steel, and has racks deep enough to keep your spice jars securely in place. There’s a thin plastic sheet for the bottom of each rack. Due to the shape of the racks, I recommend using square spice jars rather than round ones. My 6 ounce square jars fit well, and each rack holds 5 jars. Or you can use the smaller 4 ounce square spice jars and fit 6 jars in each rack. The 4 ounce jars will be looser and slide around more when you pull each rack out. I also recommend getting some round ingredient labels for your jar lids so you can identify contents quickly without having to lift each jar to look at the label. The stainless steel metal is thick, smooth and well attached, with nicely rounded corners. The top row is height adjustable. Each rack has its own extension mechanism. That means when you pull out a rack, it doesn’t pull out the entire row. This is especially important if you’ve used the adhesive to attach the rack to your pantry shelf or inside a cabinet as a top heavy item will pull and loosen the adhesive over time. The rack comes with mounting adhesive and wood mounting screws and its own screwdriver, another bonus for ease of installation. You can choose to mount the rack with the adhesive or the screws. My personal preference here is to attach this rack with the provided screws rather than the adhesive. With glass jars and weight that’s being pulled out over a tile floor in a pantry or over a hard countertop, having the risk of adhesive giving way is inviting disaster. So consider all the options when deciding on how to attach it. Overall, this Boivshi Spice Rack Organizer is very well made, and is a good deal at this price point. I definitely recommend it.

Expensive, but Smooth, Sturdy Spice Rack
I received the BOIVSHI Spice Rack Organizer through the Vine program, and overall I’m quite pleased with its quality.
The rack feels sturdy and well-made. The metal construction has a solid, heavy-duty feel, and the chrome finish gives it a clean, modern look that works well in most kitchens.
The pull-out mechanism is smooth and glides nicely. The 2-tier design is efficient and makes good use of vertical space. Installation was fairly easy and the instructions are simple enough to follow.
For me, it is limited to smaller spice bottles, due to the configuration of my cabinet which limits the available height of the top tier. Also, the rack has to be secured to the surface, either with screws or adhesive mount, to prevent it from sliding around.
Overall, it is well made and a practical solution for organizing spices. If your cabinet dimensions are compatible and you mostly use standard-size spice jars, it’s a solid upgrade that makes everyday cooking more convenient.
However, this is a very expensive spice rack, if you compare it to similar items.

Good size, looks nice, mostly easy to put together and install
Okay I love this a lot more than I expected to. I was not extremely excited about the instructions. They come with a warning that if you have any doubts about your ability to install this, call a qualified technician. It just seemed condescending. Also, everything is printed poorly, like someone put this together in the 80's and it printed smudgingly and this is the copies from that. The only thing that this made confusing was when trying to figure out where the cabinet screws go (before I realized that was an alternative install), you really can't tell which holes they go in. Turns out they probably go in the holes covered by the pre-installed sticky PVC mat.
Only other issue I had was that it comes with a screwdriver. It seems so wasteful to include something that should be in every household, especially those who buy diy things like this.
But beyond that, everything else is great. It was easy to put together, it was easy to place in the cupboard, and it was easy to fill.
I love that each line comes out individually. It's nice and sturdy. I tried pulling on it to test it, and the sticky was strong.
I mostly loved that, even though this took up 3/4 of the shelf, I was able to fit all my small spices AND my honey AND my sprinkles. I went from 3 overflowing shelves to 2 full shelves and an almost empty one. I only have 6 items on the top. I feel super happy about this.
