Price and Final Thoughts

In October 2015, ABUniverse (ABU) released Space, its first completely new diaper since being bought out and relaunched under new management at the beginning of that year. ABU followed up in early 2016 with two additional prints: a furry print, LittlePawz, and an all-white unprinted and lower-priced version, Simple. Space was released with substantial marketing fanfare, and proceeded to deliver on that hype, becoming one of the highest capacity ABDL diapers ever released and a benchmark diaper that was not seriously challenged in the US market for about 2 years.I am reviewing the medium size LittlePawz, Space, and Simple diapers as purchased for review in January 2018. The small is listed as fitting waists of 22"-29", the medium is listed as fitting waists of 31"-36", the large is listed as fitting waists of 37"-44", and the extra-large is listed as fitting waists of 45"-52".The ABU LittlePawz, Space, and Simple have packaging similar to other ABU products with printed panels partially filling the front of on other otherwise transparent package. The LittlePawz panel has its logos and character art, the Space panel has an alien and the letter denoting size filled in with the print, and the Simple panel is just the letter denoting size by itself.The ABU LittlePawz has an all-over furry-themed print made in collaboration with prominent babyfur artist MarciMcAdam. The print features a white center with pawprints as a wetness indicator in the very center with baby animal characters and baby items to the sides, bordered by wavy blue dotted line on the sides of the diaper, and a green and blue plaid pattern on the wings. A glossy, transparent landing zone lies over the front. The design is certainly unique, and has babyish elements to it, but it's unlike any baby diaper print I can think of. It's more of a "what-if" furry print than it is authentic.The ABU Space has an all-over space-themed print, with a blue background, orange and red space-related icons on the sides, and fade-when-wet green aliens filling most of the space in the middle. The design is colorful but the blue base color predominates. A glossy, transparent landing zone lies over the front. It's an interesting and unique idea for a diaper print, where one "fights" the aliens as one uses the diaper and causes them to fade, sort of a "diaper as game" concept. It's not a babyish design at all, with toothy aliens and aliens holding ray guns; this is a pattern more age-appropriate for a grade-school boys.The ABU Simple is an all-white diaper, with a transparent glossy tape panel that has the ABU logo and size at the sides, presumably to help guide placement of tapes.The outer plastic of these diapers has a slick, oily feel to it, and feels substantial. The plastic on Simple seems a bit less slick in my hands than on LittlePawz and Space.To test their dry thickness, I stacked three diapers on top of each other, placed a heavy book on top of them, and measured their height. Together, the 3 diapers had a height of approximately 9.0 cm (3.5 in). Thus, the dry thickness of a single folded diaper is 3.0 cm (1.2 in).These diapers use a double-tape design with tapes that measure 4.1 cm (1.6 in) wide each.The insides of these diapers are all white, arranged in an hourglass shape, and soft. The material has a cotton feel that is neither particularly packed nor diffuse. These diapers have standing leak guards and an elastic waistband in the front and back.With the diaper outstretched, it measures 76.5 cm (30.1 in) in length, 65.0 cm (25.6 in) in width at the wings, 32.2 cm (12.7 in) in width at the center, and 23.3 cm (9.2 in) in width between the leak guards.To test the capacity of this diaper quantitatively, I performed two tests.First, I weighed a diaper and put it on. I then repeatedly dosed water into the front of it in 100 mL increments using a metered laboratory bottletop dispenser, followed by sitting down in a chair for 30 seconds each time to give the diaper a chance to absorb the liquid, then checking for leaks. When a leak occurred, I weighed the diaper again, and recorded the change in weight.Over 4 replicates of this H2O capacity test, a mixed selection of the three diapers averaged 2438 mL with a standard deviation of 91 mL.During a previous trial of this test, I recorded qualitative information about the diaper as I added water to it. After 900 mL of water, I first noticed liquid running near the legs. At 1200 mL, it felt generally moist to sit in. At 1800 mL, I felt like I was sitting in a puddle. At 2200 mL, I felt like I was sitting in a pond. At 2400 mL, I felt wetness at the cuffs and the diaper started to leak.I folded the diaper back up to compare its thickness to a dry diaper. It measured roughly 11.6 cm (4.5 in), roughly 3.1x its original size.The tapes held steady through all of these trials.I then performed a second test in which I made normal saline (0.9% NaCl in H2O), weighed a diaper and put it on, then used a metered laboratory bottletop dispenser to dose 160 mL saline every 5 minutes until it leaked, sitting down between increments. I weighed the diaper afterwards and divided the resulting change in grams by 1.0046 to account for the density of saline to determine the change in milliliters. 160 mL is approximately equivalent to half of an average adult urine void, and this increment is loosely representative of a "half-flood".Over 3 replicates of this saline capacity test, a mixed selection of the 3 diapers averaged 1021 mL with a standard deviation of 89 mL. Rounded to numbers of integer "half-flood" doses, the diaper averaged 6.3 "half-floods" with a standard deviation of 0.6 "half-floods".The average dry mass of this diaper, based on 7 replicates across both tests, was 211.9 g with a standard deviation of 3.0 g.I weighed and put on a fresh diaper and wore it while going about ordinary activities. The diaper lasted a total of 4.5 hours before beginning to leak. During my test, I had 5 moderate wettings and then flooded it, causing it to leak. I measured a change of 1278 g or roughly 8.0 "half-floods", which is towards the high end of what would be expected from my test results but consistent with filling the diaper to near-capacity and then leaking on a flood.With a 36" waist, I am at the top of the listed size range for the medium LittlePawz, Space, and Simple. I normally wear size medium in other diaper brands. The fit was similar to other mediums, and this diaper fit thickly but comfortably. The tapes held firm on these diapers during my tests, and I have anecdotally had only infrequent issues with tapes sliding on these diapers since the move to the current clear tapes.I bought packs of these diapers for the purposes of a review from https://abuniverse.com/ . Without shipping, ABU LittlePawz and ABU Space are available as single samples for $6.00 (with a $5 discount for a future order for every two sample diapers ordered across brands), 10-diaper packs for $34.99, 40-diaper half-cases for $84.99, and 80-diaper cases at $155.99. Without shipping, ABU LittlePawz and ABU Space are available in 2-diaper sample packs for $6.00, 10-diaper packs for $32.99, 40-diaper half-cases for $78.99, and 80-diaper cases at $134.99. ABU no longer includes shipping in its prices, and now adds $1 for samples, $5 for single packs, $8 for half-cases, and $12 for cases, bringing the final case price to $167.99 for LittlePawz and Space and $145.99 for Simple.At the case size, this works out for LittlePawz and Space to $2.10/diaper which based on my test results means these diaper holds 3.0 "half-floods" per dollar, and to $1.84/diaper for Simple which based on my test results works out to 3.4 "half-floods" per dollar. LittlePawz and Space are priced near the middle of the pack amongst ABDL diapers while Simple is priced towards the cheaper end. Given their excellent capacity and reasonable pricing, all three diapers are in the top third in terms of efficiency of capacity for price.For nearly two years, these diapers set the gold standard for ABDL diapers in America, and have only recently been challenged with their lead having eroded due to multiple developments in the past 6 months. Tykables released new Overnights diapers at a matching price point with similar capacity and additional features, NorthShoreCare made Thrust Vector Crinklz widely and cheaply available in America for the first time, and the recent addition of a shipping surcharge amounted to a nearly 8% price hike which was enough to shift their position behind a couple closely competing diapers. On top of all of that, ABU itself is taking the step to surpass their previous benchmark with the impending release of PeekABU and Simple Ultra at an even higher tier of capacity.ABU LittlePawz, Space, and Simple remain among the best overall diapers on the market today – they just no longer lead the pack. The market has caught up and US customers now have several other similarly high-quality options to choose amongst including a few that I'd say edge them out in the contest for best overall. They are still a great buy and continue to stand tall on the "super-premium" tier that ABU Space was among the very ABDL diapers to define in 2015.
