Delivered very quickly; super professional.

Replaced the belts in my Awia ADF770, then used the test tape to check speed using a windows based software wow & flutter meter. New belts, a clean amd lubriation fixed flutter issues, but still seeing speed variations. Have ordered a new capstan motor - will replace and retest. The Duplication test tape arrived promptly, was well packaged and worked great - could not complete the repair without it - nice job!

Good solid case with good positive closure clips. Also have great centre clips for expandability using the 'snap-in' expander trays that are available as a separate item!

Good quality cassettes, didn't feel flimsy or cheaply made. Would definitely recommend if you're looking to buy some.

I recommend using the pdf template and printing your covers out on glossy brochure paper instead of on these. When you start to tear the J-cards at the perforations they leave these tiny residual marks on the sides of the cover. There's always a chance the the J-card can split since each panel is perforated too.

Good quality stickers, just be extra careful when applying them onto the cassette. Would recommend!

Love these cases. They feel very sturdy, and the square corners are very classy.

I ordered the 5-dvd disc cases and I WAS THOROUGHLY PLEASED with the items. Not only were they well-packaged, but very sturdily built! I have ordered similar cases from others in the past, only to have them held in place by pins. Instead, I found these to be very strong, and the inner holders stay snugly in place. I will continue to be a loyal customer as more are needed. A pleasure to do business with. Thank you!

I ordered the 6-dvd disc cases and I WAS THOROUGHLY PLEASED with the items. Not only were they well-packaged, but very sturdily built!

This speed calibration tape is Infinitely useful. I have multiple decks that I run, and this speed test tape helps keep each deck running at the same speed and has saved me countless headaches

Disappointed with the quality, they all have scratches on them. Ordered 12 of these, 9 of them had one or two noticeably bad scratches on the front. The other 3 also had scratches but weren't as noticeable from afar. I will have to buy new ones from Amazon, do not recommend...

They look great fit to a tee and the colors are sharp

These cd single boxes are perfect for european cd singles with a j card. They have a frozen tray. They are packaged very well. So buy these at duplication.ca. A highly recommended seller!

Great mailers, U-line without the higher price.

Wasn't sure about buying these tapes, but as I wanted some custom length thought I would give them a try. Pleased with the results I have achieved. Using a high end Teac with adjustable level and bias. Shipping seemed a little high though.

Looks good on the cassettes.

An excellent product, exactly what was needed. They shipped quickly and were packaged properly.

These fit the records and the sleeves perfectly. The offset opening makes it easy to put the record in

Very happy with this product - the quality is great and the price even better! Great value for money! I have had many positive reviews from customers on the quality of packaging. Very happy!! Note:
with the elaborate gatefold sleeve's of today's LPs, it's likely that you will get 3 to 4 LPs in this mailer - not the 5 to 6 LPs as advertised. But certainly not a deal breaker for me.

Very good service. After mistakenly ordering the wrong item we had no problem exchanging them. Very helpful staff. Would definitely use them again.

English translation:
Excellent product! I fitted a Teac deck and some pretty good Sony walkmans. In my case I adjusted them with free software from Techmind.org, http://www.techmind.org/audio/index.html
With the Tuner (Frequency-counter / instrument-tuner)
I also used wow & flutter meter(WFGUI wow & flutter meter) by Alex Fred from http://www.ant-audio.co.uk/index.php?cat=post&qry=library
The latter was suggested in a Techmoan Youtube video, https://www.youtube.com/watch?v=0G2kU1e9Cpo
I used the second one, for the first one the 440hz tone of the cassette is recommended
The only inconvenience was with the shipping company that they did not make the shipment with tracking, but duplication.ca responded immediately, they told me that if the product did not arrive on a certain date they would send me another one at no cost, this was not necessary, since It arrived without any problem. Totally reliable and safe purchases in duplication.ca
Thank you very much from Mexico.
Thank you duplication.ca!!!

Original Spanish review:
Excelente producto! Ajusté un deck Teac y algunos walkman Sony muy correctos. En mi caso los ajusté con un software libre de Techmind.org, http://www.techmind.org/audio/index.html
Con el Afinador (Frequency-counter / instrument-tuner)
También usé medidor de wow & flutter(WFGUI wow & flutter meter) de Alex Fred del sitio http://www.ant-audio.co.uk/index.php?cat=post&qry=library
Este último fue sugerido en un video de Techmoan en Youtube, https://www.youtube.com/watch?v=0G2kU1e9Cpo
Yo usé el segundo, para el primero es recomendable el tono de 440 hz del cassette
El único inconveniente fue con la compañía de envío que no hicieron el envío con rastreo, pero duplication.ca respondieron de inmediato, me dijeron que si no llegaba el producto en determinada fecha ellos me enviarían otro sin costo, esto no fue necesario, ya que llegó sin más problema. Totalmente confiables y seguras las compras en duplicatión.ca
Muchas gracias desde México.
Thank you duplication.ca!!!

It's very nice tape. I ordered because it was on sale, probably clearance... but I didn't notice that it's 1/8" when I actually wanted 1/4". Whoops!

I bought these to replace some aging / cracked double cassette tapes I got in the 90s. The front side of the case where the j-card is inserted is slightly smaller than the width of the old cases which causes the j-card to be bent in order to fit inside.

The other issue is there's a small white dot on the spine of the cases from the manufacturing process which looks ugly when you have the cases on display. It gets in the way of reading what's on the spine of the j-card. Here's an example: https://i.imgur.com/7SaSbf1.jpg

Other than that these are fine. Honestly, these were the only double cassette cases I could find in North America so I suppose there are no other options. I wish they could at least find a way to manufacture them without leaving a dot in the middle of the spines. Cases from the 90s didn't have this issue. And single cassette cases don't either.

Very good quality, I use them for my DIY tapes. Staff/customer service is VERY friendly and understanding. I recommended this brand to multiple friends!

good quality pad for a good price.
